.SH DESCRIPTION
|
||||
.
|
||||
hwloc-annotate loads a topology from a XML file, adds some annotations,
|
||||
and export the resulting topology to another XML file.
|
||||
The input and output files may be the same.
|
||||
.
|
||||
.PP
|
||||
The annotation may be string info attributes.
|
||||
This is specified by the \fImode\fR:
|
||||
.
|
||||
.TP
|
||||
.B info <name> <value>
|
||||
Specifies a new string info attribute whose name is \fIname\fR and
|
||||
value is \fIvalue\fR.
|
||||
.TP
|
||||
.B subtype <subtype>
|
||||
Specifies that the subtype attribute of the object should now be \fIsubtype\fR.
|
||||
If an empty string is given, the subtype is removed.
|
||||
.TP
|
||||
.B size <size>
|
||||
Specifies the size of a cache or NUMA node.
|
||||
The value may be suffixed with \fBkB\fR, \fBKiB\fR, \fBMB\fR, \fBMiB\fR,
|
||||
\fBGB\fR, \fBGiB\fR, etc.
|
||||
.TP
|
||||
.B misc <name>
|
||||
Specifies a new Misc object name.
|
||||
.TP
|
||||
.B memattr <name> <flags>
|
||||
Register a new memory attribute whose name is \fIname\fR and
|
||||
flags is \fIflags\fR.
|
||||
\fIlocation\fR is ignored in this mode.
|
||||
|
||||
Flags may be given as numeric values or as a comma-separated list of flag names
|
||||
that are passed to \fIhwloc_memattr_register()\fR.
|
||||
Those names may be substrings of actual flag names as long as a single one matches.
|
||||
For instance, a value of \fB1\fR (or \fBhigher\fR) means that
|
||||
highest values are considered best for this attribute.
|
||||
.TP
|
||||
.B memattr <name> <initiator> <value>
|
||||
Set the memory attribute (whose name is \fIname\fR)
|
||||
from initiator \fIinitiator\fR (either an object or a CPU-set)
|
||||
to target NUMA node \fIlocation\fR
|
||||
to value \fIvalue\fR.
|
||||
|
||||
If this attribute does not require specific initiators,
|
||||
\fIinitiator\fR is ignored.
|
||||
|
||||
Standard attribute names are \fICapacity\fR, \fILocality\fR,
|
||||
\fIBandwidth\fR, and \fILatency\fR.
|
||||
All existing attributes in the input topology may be listed with
|
||||
|
||||
$ lstopo --memattrs -i input.xml
|
||||
|
||||
.TP
|
||||
.B cpukind <cpuset> <efficiency> <flags> [<infoname> <infovalue>]
|
||||
Specifies the kind of CPU for PUs listed in the given cpuset.
|
||||
\fIlocation\fR is ignored in this mode.
|
||||
|
||||
\fIefficiency\fR is an abstracted efficiency value that will enforce
|
||||
ranking of kinds. It should be -1 if unknown.
|
||||
|
||||
\fIflags\fR must be 0 for now.
|
||||
|
||||
If \fIinfoname\fR and \fIinfovalue\fR are given and non-empty,
|
||||
they are added as info attributes to this kind of CPU.
|
||||
|
||||
See the function hwloc_cpukinds_register() for details.
|
||||
|
||||
.TP
|
||||
.B distances <filename> [<flags>]
|
||||
Specifies new distances to be added to the topology using specifications in \fI<filename>\fR.
|
||||
The optional \fIflags\fR (0 unless specified) corresponds to the flags
|
||||
given to the function \fBhwloc_distances_set()\fR.
|
||||
\fIlocation\fR is ignored in this mode.
|
||||
|
||||
The real first line of the pointed file must be a integer representing
|
||||
a distances \fBkind\fR as defined in \fBhwloc/distances.h\fR.
|
||||
The second line is the number of objects involved in the distances.
|
||||
The next lines contain one object each.
|
||||
The next lines contain one distance value each,
|
||||
or a single line may be given with a integer combination of format \fBx*y\fR or \fBx*y*z\fR.
|
||||
An optional line before all others may start with \fBname=\fR
|
||||
to specify the name of the distances structure if any.
|
||||
|
||||
.TP
|
||||
.B distances-transform <name> links
|
||||
Transform a bandwidth distances structure named <name> into links.
|
||||
See the documentation of HWLOC_DISTANCES_TRANSFORM_LINKS in hwloc/distances.h for details.
|
||||
.TP
|
||||
.B distances-transform <name> merge-switch-ports
|
||||
When switches appear in the matrix as different ports, merge all of them
|
||||
into a single port for clarity.
|
||||
This currently only applies to the NVLinkBandwidth matrix between NVIDIA GPUs.
|
||||
See the documentation of HWLOC_DISTANCES_TRANSFORM_MERGE_SWITCH_PORTS in hwloc/distances.h for details.
|
||||
.TP
|
||||
.B distances-transform <name> transitive-closure
|
||||
If objects are connected across a switch, apply a transitive-closure
|
||||
to report the bandwidth through that switch.
|
||||
This currently only applies to the NVLinkBandwidth matrix between NVIDIA GPUs.
|
||||
The bandwidth between all pairs of GPUs will be exposed instead of
|
||||
bandwidths between single GPUs and single NVSwitch ports.
|
||||
See the documentation of HWLOC_DISTANCES_TRANSFORM_TRANSITIVE_CLOSURE in hwloc/distances.h for details.
|
||||
.TP
|
||||
.B distances-transform <name> remove-obj <obj>
|
||||
Remove the given object from the distances structure named <name>.
|
||||
.TP
|
||||
.B distances-transform <name> replace-objs <oldtype> <newtype>
|
||||
Replace objects of type <oldtype> in distances structure named <name>
|
||||
with objects of type <newtype> with same locality.
|
||||
If <oldtype> or <newtype> are not object types, they are assumed
|
||||
subtypes of OS devices, e.g. "NVML" or "OpenCL".
|
||||
See the documentation of hwloc_get_obj_with_same_locality() in hwloc/helper.h for details.
|
||||
|
||||
If <newtype> is "NULL", objects are removed from the distances structure.
|
||||
|
||||
.TP
|
||||
.B none
|
||||
No new annotation is added. This is useful when clearing existing attributes.
|
||||
.
|
||||
.PP
|
||||
Annotations may be added to one specific object in the topology,
|
||||
all of them, or all of a given type.
|
||||
This is specified by the \fIlocation\fR (see also EXAMPLES below).
|
||||
Multiple locations may be affected if they are specified between \fB--\fR.
|
||||
Objects may be specified as location tuples, as explained in hwloc(7).
|
||||
However hexadecimal bitmasks are not accepted since they may correspond to multiple objects.
|
||||
.
|
||||
.PP
|
||||
.B NOTE:
|
||||
The existing annotations may be listed with hwloc-info.
|

|
||||
It is highly recommended that you read the hwloc(7) overview page
|
||||
before reading this man page. Most of the concepts described in

.SH EXAMPLES
|
||||
.PP
|
||||
hwloc-annotate's operation is best described through several examples.
|
||||
.
|
||||
.PP
|
||||
Add an info attribute to all Core and PU objects:
|
||||
|
||||
$ hwloc-annotate input.xml output.xml -- Core:all PU:all -- info infoname infovalue
|
||||
|
||||
Only add to all Core objects:
|
||||
|
||||
$ hwloc-annotate input.xml output.xml Core:all info infoname infovalue
|
||||
|
||||
Add a Misc object named "foobar" under the root object of the topology
|
||||
and modify the input XML directly:
|
||||
|
||||
$ hwloc-annotate file.xml file.xml root misc foobar
|
||||
|
||||
Add an info attribute to OS device #2 and #3:
|
||||
|
||||
$ hwloc-annotate input.xml output.xml os:2-3 info infoname infovalue
|
||||
|
||||
Change package objects to green with red text in the lstopo graphical output:
|
||||
|
||||
$ hwloc-annotate topo.xml topo.xml package:all info lstopoStyle "Background=#00ff00;Text=#ff0000"
|
||||
$ lstopo -i topo.xml
|
||||
|
||||
Set the memory attribute latency to 123 nanoseconds from the PUs in the first package to the first NUMA node:
|
||||
|
||||
$ hwloc-annotate topo.xml topo.xml numanode:0 memattr Latency $(hwloc-calc package:0) 123
|
||||
|
||||
Register a memory attribute \fBMyApplicationPerformance\fR
|
||||
(with flags specifying that it requires an initiator and reports higher values first)
|
||||
and set its value for initiator CPU-set 0x11 to NUMA node #2 to 2345:
|
||||
|
||||
$ hwloc-annotate topo.xml topo.xml ignored memattr MyApplicationPerformance need_init,higher
|
||||
$ hwloc-annotate topo.xml topo.xml numanode:2 memattr MyApplicationPerformance 0x11 2345
|
||||
|
||||
To clarify that NUMA node #0 is DDR while NUMA node #1 is HBM:
|
||||
|
||||
$ hwloc-annotate topo.xml topo.xml numa:0 subtype DDR
|
||||
$ hwloc-annotate topo.xml topo.xml numa:1 subtype HBM
|
||||
|
||||
Specify that PU 0-3 and PU 4-7 are of different kinds, and the latter is more efficient:
|
||||
|
||||
$ hwloc-annotate topo.xml topo.xml dummy cpukind 0x0f 0 0 CoreType Small
|
||||
$ hwloc-annotate topo.xml topo.xml dummy cpukind 0xf0 1 0 CoreType Big
|
||||
|
||||
Replace NUMA nodes with Packages in the NUMALatency distances matrix,
|
||||
when they have the exact same locality.
|
||||
|
||||
$ hwloc-annotate topo.xml topo.xml -- dummy -- distances-transform NUMALatency replace-objs numanode packages
|
||||
|
||||
Remove NUMA node #3 from the NUMALatency distances matrix:
|
||||
|
||||
$ hwloc-annotate topo.xml topo.xml -- dummy -- distances-transform NUMALatency remove-obj numa:3
|
||||
|
||||
Merge all NVSwitch ports bandwidth information into a single port in the NVLinkBandwidth matrix:
|
||||
|
||||
$ hwloc-annotate topo.xml topo.xml -- dummy -- distances-transform NVLinkBandwidth merge-switch-ports
|
||||
|
||||
Apply a transitive closure to get inter-GPU bandwidth across NVSwitches in the NVLinkBandwidth matrix:
|
||||
|
||||
$ hwloc-annotate topo.xml topo.xml -- dummy -- distances-transform NVLinkBandwidth transitive-closure
|
||||

at the memory attribute given by \fI<name>\fR (or as an index).
|
||||
|
||||
If the memory attribute values depend on the initiator, the CPU binding

.SH DESCRIPTION
|
||||
.
|
||||
hwloc-bind execs an executable (with optional command line arguments)
|
||||
that is bound to the specified location (or list of locations).
|
||||
Location specification is described in hwloc(7).
|
||||
Upon successful execution, hwloc-bind simply sets bindings and then execs
|
||||
the executable over itself.
|
||||
.
|
||||
.PP
|
||||
If a bitmask location is given with prefix \fInodeset=\fR, then it
|
||||
is considered a nodeset instead of a CPU set. See also \fB\-\-nodeset\fR.
|
||||
.
|
||||
.PP
|
||||
If multiple locations are given, they are combined in the sense that
|
||||
the binding will be wider. The process will be allowed to run on every
|
||||
location inside the combination.
|
||||
.
|
||||
.PP
|
||||
The list of input locations may be explicitly ended with "--".
|
||||
.
|
||||
.PP
|
||||
If binding fails, or if the binding set is empty, and \fB\-\-force\fR
|
||||
was not given, hwloc-bind returns with an error instead of launching
|
||||
the executable.
|
||||
.
|
||||
.PP
|
||||
.B NOTE:
|
||||
It is highly recommended that you read the hwloc(7) overview page
|
||||
before reading this man page. Most of the concepts described in
|
||||
hwloc(7) directly apply to the hwloc-bind utility.

.\" **************************
|

.\" Examples Section
|
||||
.\" **************************
|
||||
.SH EXAMPLES
|
||||
.PP
|
||||
hwloc-bind's operation is best described through several examples.
|
||||
More details about how locations are specified on the hwloc-bind
|
||||
command line are described in hwloc(7).
|
||||
.
|
||||
.PP
|
||||
To run the echo command on the first logical processor of the second
|
||||
package:
|
||||
|
||||
$ hwloc-bind package:1.pu:0 -- echo hello
|
||||
|
||||
which is exactly equivalent to the following line as long as there is
|
||||
no ambiguity between hwloc-bind option names and the executed command name:
|
||||
|
||||
$ hwloc-bind package:1.pu:0 echo hello
|
||||
|
||||
To bind the "echo" command to the first core of the second package and
|
||||
the second core of the first package:
|
||||
|
||||
$ hwloc-bind package:1.core:0 package:0.core:1 -- echo hello
|
||||
|
||||
To bind on the first PU of all cores of the first package:
|
||||
|
||||
$ hwloc-bind package:0.core:all.pu:0 -- echo hello
|
||||
$ hwloc-bind --no-smt package:0 -- echo hello
|
||||
|
||||
To bind on the memory node local to a PU with largest capacity:
|
||||
|
||||
$ hwloc-bind --best-memattr capacity --cpubind pu:23 --membind pu:23 -- echo hello
|
||||
|
||||
To bind memory on the first high-bandwidth memory node on Intel Xeon Phi:
|
||||
|
||||
$ hwloc-bind --membind hbm:0 -- echo hello
|
||||
$ hwloc-bind --hbm --membind numa:0 -- echo hello
|
||||
|
||||
Note that binding the "echo" command to multiple processors is
|
||||
probably meaningless (because "echo" is likely implemented as a
|
||||
single-threaded application); these examples just serve to show what
|
||||
hwloc-bind can do.
|
||||
.
|
||||
.PP
|
||||
To run on the first three packages on the second and third nodes:
|
||||
|
||||
$ hwloc-bind node:1-2.package:0:3 -- echo hello
|
||||
|
||||
which is also equivalent to:
|
||||
|
||||
$ hwloc-bind node:1-2.package:0-2 -- echo hello
|
||||
|
||||
Note that if you attempt to bind to objects that do not exist,
|
||||
hwloc-bind will not warn unless
|
||||
.I -v
|
||||
was specified.
|
||||
|
||||
To run on processor with physical index 2 in package with physical index 1:
|
||||
|
||||
$ hwloc-bind --physical package:1.core:2 -- echo hello
|
||||
|
||||
To run on odd cores within even packages:
|
||||
|
||||
$ hwloc-bind package:even.core:odd -- echo hello
|
||||
|
||||
To run on the first package, except on its second and fifth cores:
|
||||
|
||||
$ hwloc-bind package:0 ~package:0.core:1 ~package:0.core:4 -- echo hello
|
||||
|
||||
To run anywhere except on the first package:
|
||||
|
||||
$ hwloc-bind all ~package:0 -- echo hello
|
||||
|
||||
To run on a core near the network interface named eth0:
|
||||
|
||||
$ hwloc-bind os=eth0 -- echo hello
|
||||
|
||||
To run on a core near the PCI device whose bus ID is 0000:01:02.0:
|
||||
|
||||
$ hwloc-bind pci=0000:01:02.0 -- echo hello
|
||||
|
||||
To bind memory on second memory node and run on first node (when supported by the OS):
|
||||
|
||||
$ hwloc-bind --cpubind node:1 --membind node:0 -- echo hello
|
||||
|
||||
The --get option can report current bindings. This example shows
|
||||
nesting hwloc-bind invocations to set a binding and then report it:
|
||||
|
||||
$ hwloc-bind node:1.package:2 -- hwloc-bind --get
|
||||
0x00004444,0x44000000
|
||||
|
||||
hwloc-calc can also be used to convert cpu mask strings to
|
||||
human-readable package/core/PU strings; see the description of -H in
|
||||
hwloc-calc(1) for more details. The following example binds to all
|
||||
the PUs in a specific core, uses the --get option to retrieve where
|
||||
the process was actually bound, and then uses hwloc-calc to display
|
||||
the resulting cpu mask in space-delimited list of human-readable
|
||||
locations:
|
||||
|
||||
$ hwloc-bind package:1.core:2 -- hwloc-bind --get | hwloc-calc -H package.core.pu
|
||||
Package:1.Core:2.PU:0 Package:1.Core:2.PU:1
|
||||
|
||||
hwloc-calc may convert this output into actual objects, either with logical or physical indexes:
|
||||
|
||||
$ hwloc-calc --physical -I pu `hwloc-bind --get`
|
||||
26,30,34,38,42,46
|
||||
$ hwloc-calc --logical -I pu `hwloc-bind --get` --sep " "
|
||||
24 25 26 27 28 29
|
||||
|
||||
.
|
||||
.PP
|
||||
Locations may also be specified as a hex bit mask (typically generated
|
||||
by hwloc-calc). For example:
|
||||
|
||||
$ hwloc-bind 0x00004444,0x44000000 -- echo hello
|
||||
$ hwloc-bind `hwloc-calc node:1.package:2` -- echo hello
|
||||
|
||||
The current memory binding may also be reported:
|
||||
|
||||
$ hwloc-bind --membind node:1 --mempolicy interleave -- hwloc-bind --get --membind
|
||||
0x000000f0 (interleave)
|
||||
|
||||
.SH HINT
|
||||
If the graphics-enabled lstopo is available, use for instance
|
||||
|
||||
$ hwloc-bind core:2 -- lstopo --pid 0
|
||||
|
||||
to check what the result of your binding command actually is.
|
||||
lstopo will graphically show where it is bound to by hwloc-bind.

||||

|

.SH RETURN VALUE
|

Upon successful execution, hwloc-bind execs the command over itself.
|

The return value is therefore whatever the return value of the command
|
||||
is.
|
||||
.
|
||||
.PP
|
||||
hwloc-bind will return nonzero if any kind of error occurs, such as
|
||||
(but not limited to): failure to parse the command line, failure to
|
||||
retrieve process bindings, or lack of a command to execute.

\fB\-\-no\-smt\fR, \fB\-\-no\-smt=<N>\fR
|
||||
Only keep the first PU per core in the input locations.
|
||||
If \fI<N>\fR is specified, keep the <N>-th instead, if any.
|
||||
PUs are ordered by physical index during this filtering.
|

.TP
|
||||
\fB\-\-cpukind\fR <n>
|
||||
\fB\-\-cpukind\fR <infoname>=<infovalue>
|

Only keep PUs whose CPU kind match.
|
||||
Either a single CPU kind is specified as an index,
|
||||
or the info name/value keypair will select matching kinds.
|
||||
|
||||
When specified by index, it corresponds to hwloc ranking of CPU kinds
|
||||
which returns energy-efficient cores first, and high-performance
|

The full list of CPU kinds may be seen with \fIlstopo --cpukinds\fR.
|

.TP
|

\fB\-\-restrict\fR <cpuset>
|
||||
Restrict the topology to the given cpuset.
|
||||
.TP
|

\fB\-\-restrict\fR nodeset=<nodeset>
|
||||
Restrict the topology to the given nodeset, unless \fB\-\-restrict\-flags\fR specifies something different.
|
||||
.TP
|
||||
\fB\-\-restrict\-flags\fR <flags>
|
||||
Enforce flags when restricting the topology.
|
||||
Flags may be given as numeric values or as a comma-separated list of flag names
|
||||
that are passed to \fIhwloc_topology_restrict()\fR.
|
||||
Those names may be substrings of actual flag names as long as a single one matches,
|

for instance \fBbynodeset,memless\fR.
|

The default is \fB0\fR (or \fBnone\fR).
|

.TP
|

\fB\-\-disallowed\fR
|
||||
Include objects disallowed by administrative limitations.
|
||||
.TP
|
||||
\fB\-i\fR <path>, \fB\-\-input\fR <path>
|
||||
Read the topology from <path> instead of discovering the topology of the local machine.
|
||||
|
||||
If <path> is a file and XML support has been compiled in hwloc,
|
||||
it may be a XML file exported by a previous hwloc program.
|
||||
If <path> is "\-", the standard input may be used as a XML file.
|
||||
|
||||
On Linux, <path> may be a directory containing the topology files
|
||||
gathered from another machine topology with hwloc-gather-topology.
|
||||
|
||||
On x86, <path> may be a directory containing a cpuid dump gathered
|

with hwloc-gather-cpuid.
|
||||
|

.TP
|
||||
\fB\-i\fR <specification>, \fB\-\-input\fR <specification>
|

Simulate a fake hierarchy (instead of discovering the topology on the
|
||||
local machine). If <specification> is "node:2 pu:3", the topology will
|
||||
contain two NUMA nodes with 3 processing units in each of them.

\fB\-p\fR \fB\-\-physical\fR
|

Use OS/physical indexes instead of logical indexes for both input and output.
|
||||
.TP
|
||||
\fB\-l\fR \fB\-\-logical\fR
|
||||
Use logical indexes instead of physical/OS indexes for both input and output (default).
|

\fB\-\-pi\fR \fB\-\-physical\-input\fR
|

Use OS/physical indexes instead of logical indexes for input.
|

\fB\-\-po\fR \fB\-\-physical\-output\fR
|

Use OS/physical indexes instead of logical indexes for output.
|

.TP
|
||||
\fB\-\-lo\fR \fB\-\-logical\-output\fR
|
||||
Use logical indexes instead of physical/OS indexes for output (default, except for cpusets which are always physical).
|
||||
.TP
|
||||
\fB\-n\fR \fB\-\-nodeset\fR
|
||||
Interpret both input and output sets as nodesets instead of CPU sets.
|
||||
See \fB\-\-nodeset\-output\fR and \fB\-\-nodeset\-input\fR below for details.
|
||||
.TP
|
||||
\fB\-\-no\fR \fB\-\-nodeset\-output\fR
|
||||
Report nodesets instead of CPU sets.
|
||||
This output is more precise than the default CPU set output when memory
|
||||
locality matters because it properly describes CPU-less NUMA nodes,
|
||||
as well as NUMA-nodes that are local to multiple CPUs.
|
||||
.TP
|
||||
\fB\-\-ni\fR \fB\-\-nodeset\-input\fR
|
||||
Interpret input sets as nodesets instead of CPU sets.
|
||||
.TP
|
||||
\fB\-N \-\-number\-of <type|depth>\fR
|
||||
Report the number of objects of the given type or depth that intersect the CPU set.
|
||||
This is convenient for finding how many cores, NUMA nodes or PUs are available
|
||||
in a machine.
|
||||
|
||||
When combined with \fB\-\-nodeset\fR or \fB\-\-nodeset-output\fR,
|
||||
the nodeset is considered instead of the CPU set for finding matching objects.
|
||||
This is useful when reporting the output as a number or set of NUMA nodes.
|
||||
|
||||
If an OS device subtype such as \fIgpu\fR is given instead of \fIosdev\fR,
|
||||
only the os devices of that subtype will be counted.
|
||||
.TP
|
||||
\fB\-I \-\-intersect <type|depth>\fR
|
||||
Find the list of objects of the given type or depth that intersect the CPU set and
|
||||
report the comma-separated list of their indexes instead of the cpu mask string.
|
||||
This may be used for determining the list of objects above or below the input
|
||||
objects.
|
||||
|
||||
When combined with \fB\-\-physical\fR, the list is convenient to pass to external
|
||||
tools such as taskset or numactl \fB\-\-physcpubind\fR or \fB\-\-membind\fR.
|
||||
This is different from \-\-largest since the latter requires that all reported
|
||||
objects are strictly included inside the input objects.
|
||||
|
||||
When combined with \fB\-\-nodeset\fR or \fB\-\-nodeset-output\fR,
|
||||
the nodeset is considered instead of the CPU set for finding matching objects.
|
||||
This is useful when reporting the output as a number or set of NUMA nodes.
|
||||
|
||||
If an OS device subtype such as \fIgpu\fR is given instead of \fIosdev\fR,
|
||||
only the os devices of that subtype will be returned.
|
||||
.TP
|
||||
\fB\-H \-\-hierarchical <type1>.<type2>...\fR
|
||||
Find the list of objects of type <type2> that intersect the CPU set and
|
||||
report the space-separated list of their hierarchical indexes with respect
|
||||
to <type1>, <type2>, etc.
|
||||
For instance, if \fIpackage.core\fR is given, the output would be
|
||||
\fIPackage:1.Core:2 Package:2.Core:3\fR if the input contains the third
|
||||
core of the second package and the fourth core of the third package.
|
||||
|
||||
Only normal CPU-side object types should be used.
|
||||
|
||||
NUMA nodes may be used but they may cause redundancy in the output
|
||||
on heterogeneous memory platform. For instance, on a platform with both
|
||||
DRAM and HBM memory on a package, the first core will be considered both
|
||||
as first core of first NUMA node (DRAM) and
|
||||
as first core of second NUMA node (HBM).
|
||||
.TP
|
||||
\fB\-\-largest\fR
|
||||
Report (in a human readable format) the list of largest objects which exactly
|
||||
include all input objects (by looking at their CPU sets).
|
||||
None of these output objects intersect each other, and the sum of them is
|
||||
exactly equivalent to the input. No largest object is included in the input
|
||||
This is different from \-\-intersect where reported objects may not be
|
||||
strictly included in the input.
|
||||
.TP
|
||||
\fB\-\-local\-memory\fR
|
||||
Report the list of NUMA nodes that are local to the input objects.
|
||||
|
||||
This option is similar to \fB\-I numa\fR but the way nodes are selected
|
||||
is different:
|
||||
The selection performed by \fB\-\-local\-memory\fR may be precisely
|
||||
configured with \fB\-\-local\-memory\-flags\fR,
|
||||
while \fB\-I numa\fR just selects all nodes that are somehow local to
|
||||
any of the input objects.
|
||||
.TP
|
||||
\fB\-\-local\-memory\-flags\fR
|
||||
Change the flags used to select local NUMA nodes.
|
||||
Flags may be given as numeric values or as a comma-separated list of flag names
|
||||
that are passed to \fIhwloc_get_local_numanode_objs()\fR.
|
||||
Those names may be substrings of actual flag names as long as a single one matches.
|
||||
The default is \fB3\fR (or \fBsmaller,larger\fR)
|
||||
which means NUMA nodes are displayed
|
||||
if their locality either contains or is contained
|
||||
in the locality of the given object.
|
||||
|
||||
This option enables \fB\-\-local\-memory\fR.
|
||||
.TP
|
||||
\fB\-\-best\-memattr\fR <name>
|
||||
Enable the listing of local memory nodes with \fB\-\-local\-memory\fR,
|
||||
but only display the local node that has the best value for the memory
|
||||
attribute given by \fI<name>\fR (or as an index).
|
||||
|
||||
If the memory attribute values depend on the initiator, the hwloc-calc
|
||||
input objects are used as the initiator.
|
||||

.SH DESCRIPTION
|
||||
.
|
||||
hwloc-calc generates and manipulates CPU mask strings or objects.
|
||||
Both input and output may be either objects (with physical or logical
|
||||
indexes), CPU lists (with physical or logical indexes), or CPU mask strings
|
||||
(always physically indexed).
|
||||
Input location specification is described in hwloc(7).
|
||||
.
|
||||
.PP
|
||||
If objects or CPU mask strings are given on the command-line,
|
||||
they are combined and a single output is printed.
|
||||
If no object or CPU mask strings are given on the command-line,
|
||||
the program will read the standard input.
|
||||
It will combine multiple objects or CPU mask strings that are
|
||||
given on the same line of the standard input line with spaces
|
||||
as separators.
|
||||
Different input lines will be processed separately.
|
||||
.
|
||||
.PP
|
||||
Command-line arguments and options are processed in order.
|
||||
First topology configuration options should be given.
|
||||
Then, for instance, changing the type of input indexes
|
||||
with \fB\-\-li\fR or changing the input topology with \fB\-i\fR
|
||||
only affects the processing the following arguments.
|
||||
.
|
||||
.PP
|
||||
.B NOTE:
|
||||
It is highly recommended that you read the hwloc(7) overview page
|
||||
before reading this man page. Most of the concepts described in
|
||||
hwloc(7) directly apply to the hwloc-calc utility.

|
||||
.SH EXAMPLES
|
||||
.PP
|
||||
hwloc-calc's operation is best described through several examples.
|
||||
.
|
||||
.PP
|
||||
To display the (physical) CPU mask corresponding to the second package:
|
||||
|
||||
$ hwloc-calc package:1
|
||||
0x000000f0
|
||||
|
||||
To display the (physical) CPU mask corresponding to the third pacakge, excluding
|
||||
its even numbered logical processors:
|
||||
|
||||
$ hwloc-calc package:2 ~PU:even
|
||||
0x00000c00
|
||||
|
||||
To convert a cpu mask to human-readable output, the -H option can be
|
||||
used to emit a space-delimited list of locations:
|
||||
|
||||
$ echo 0x000000f0 | hwloc-calc -H package.core
|
||||
Package:1.Core1 Package:1.Core:1 Package:1.Core:2 Package:1.Core:3
|
||||
|
||||
To use some other character (e.g., a comma) instead of spaces in
|
||||
output, use the --sep option:
|
||||
|
||||
$ echo 0x000000f0 | hwloc-calc -H package.core --sep ,
|
||||
Package:1.Core1,Package:1.Core:1,Package:1.Core:2,Package:1.Core:3
|
||||
|
||||
To combine two (physical) CPU masks:
|
||||
|
||||
$ hwloc-calc 0x0000ffff 0xff000000
|
||||
0xff00ffff
|
||||
|
||||
To display the list of logical numbers of processors included in the second
|
||||
package:
|
||||
|
||||
$ hwloc-calc --intersect PU package:1
|
||||
4,5,6,7
|
||||
|
||||
To bind GNU OpenMP threads logically over the whole machine, we need to use
|
||||
physical number output instead:
|
||||
|
||||
$ export GOMP_CPU_AFFINITY=`hwloc-calc --physical-output --intersect PU all`
|
||||
$ echo $GOMP_CPU_AFFINITY
|
||||
0,4,1,5,2,6,3,7
|
||||
|
||||
To display the list of NUMA nodes, by physical indexes, that intersect a given (physical) CPU mask:
|
||||
|
||||
$ hwloc-calc --physical --intersect NUMAnode 0xf0f0f0f0
|
||||
0,2
|
||||
|
||||
To find how many cores are in the second CPU kind
|
||||
(those cores are likely higher-performance and more power-hungry than cores of the first kind):
|
||||
|
||||
$ hwloc-calc --cpukind 1 -N core all
|
||||
4
|
||||
|
||||
To display the list of NUMA nodes, by physical indexes,
|
||||
whose locality is exactly equal to a Package:
|
||||
|
||||
$ hwloc-calc --local-memory-flags 0 pack:1
|
||||
4,7
|
||||
|
||||
To display the best-capacity NUMA node, by physical indexe,
|
||||
whose locality is exactly equal to a Package:
|
||||
|
||||
$ hwloc-calc --local-memory-flags 0 --best-memattr capacity pack:1
|
||||
4
|
||||
|
||||
Converting object logical indexes (default) from/to physical/OS indexes
|
||||
may be performed with \fB--intersect\fR combined with either \fB--physical-output\fR
|
||||
(logical to physical conversion) or \fB--physical-input\fR (physical to logical):
|
||||
|
||||
$ hwloc-calc --physical-output PU:2 --intersect PU
|
||||
3
|
||||
$ hwloc-calc --physical-input PU:3 --intersect PU
|
||||
2
|
||||
|
||||
One should add \fB--nodeset\fR when converting indexes of memory objects
|
||||
to make sure a single NUMA node index is returned on platforms
|
||||
with heterogeneous memory:
|
||||
|
||||
$ hwloc-calc --nodeset --physical-output node:2 --intersect node
|
||||
3
|
||||
$ hwloc-calc --nodeset --physical-input node:3 --intersect node
|
||||
2
|
||||
|
||||
To display the set of CPUs near network interface eth0:
|
||||
|
||||
$ hwloc-calc os=eth0
|
||||
0x00005555
|
||||
|
||||
To display the indexes of packages near PCI device whose bus ID is 0000:01:02.0:
|
||||
|
||||
$ hwloc-calc pci=0000:01:02.0 --intersect Package
|
||||
1
|
||||
|
||||
To display the list of per-package cores that intersect the input:
|
||||
|
||||
$ hwloc-calc 0x00003c00 --hierarchical package.core
|
||||
Package:2.Core:1 Package:3.Core:0
|
||||
|
||||
To display the (physical) CPU mask of the entire topology except the third package:
|
||||
|
||||
$ hwloc-calc all ~package:3
|
||||
0x0000f0ff
|
||||
|
||||
To combine both physical and logical indexes as input:
|
||||
|
||||
$ hwloc-calc PU:2 --physical-input PU:3
|
||||
0x0000000c
|
||||
|
||||
To synthetize a set of cores into largest objects on a 2-node 2-package 2-core machine:
|
||||
|
||||
$ hwloc-calc core:0 --largest
|
||||
Core:0
|
||||
$ hwloc-calc core:0-1 --largest
|
||||
Package:0
|
||||
$ hwloc-calc core:4-7 --largest
|
||||
NUMANode:1
|
||||
$ hwloc-calc core:2-6 --largest
|
||||
Package:1 Package:2 Core:6
|
||||
$ hwloc-calc pack:2 --largest
|
||||
Package:2
|
||||
$ hwloc-calc package:2-3 --largest
|
||||
NUMANode:1
|
||||
|
||||
To get the set of first threads of all cores:
|
||||
|
||||
$ hwloc-calc core:all.pu:0
|
||||
$ hwloc-calc --no-smt all
|
||||
|
||||
This can also be very useful in order to make GNU OpenMP use exactly one thread
|
||||
per core, and in logical core order:
|
||||
|
||||
$ export OMP_NUM_THREADS=`hwloc-calc --number-of core all`
|
||||
$ echo $OMP_NUM_THREADS
|
||||
4
|
||||
$ export GOMP_CPU_AFFINITY=`hwloc-calc --physical-output --intersect PU --no-smt all`
|
||||
$ echo $GOMP_CPU_AFFINITY
|
||||
0,2,1,3
|
||||
|
||||
To export bitmask in a format that is acceptable by the resctrl Linux subsystem
|
||||
(for configuring cache partitioning, etc), apply a sed regexp to the output of hwloc-calc:
|
||||
|
||||
$ hwloc-calc pack:all.core:7-9.pu:0
|
||||
0x00000380,,0x00000380 <this format cannot be given to resctrl>
|
||||
$ hwloc-calc pack:all.core:7-9.pu:0 | sed -e 's/0x//g' -e 's/,,/,0,/g' -e 's/,,/,0,/g'
|
||||
00000380,0,00000380
|
||||
# echo 00000380,0,00000380 > /sys/fs/resctrl/test/cpus
|
||||
# cat /sys/fs/resctrl/test/cpus
|
||||
00000000,00000380,00000000,00000380 <the modified bitmask was corrected parsed by resctrl>
|
||||
|
||||
OS devices may also be filtered by subtype. In this example, there are
|
||||
8 OS devices in the system, 4 of them are near NUMA node #1, and only
|
||||
2 of these are CoProcessors:
|
||||
|
||||
$ utils/hwloc/hwloc-calc -I osdev all
|
||||
0,1,2,3,4,5,6,7,8
|
||||
$ utils/hwloc/hwloc-calc -I osdev node:1
|
||||
5,6,7,8
|
||||
$ utils/hwloc/hwloc-calc -I coproc node:1
|

\fB\-v\fR \fB\-\-verbose\fR
|
||||
Verbose messages.
|
||||
.TP
|
||||
\fB\-i\fR <path>, \fB\-\-input\fR <path>
|
||||
Read the topology from <path> instead of discovering the topology of the local machine.
|
||||
|
||||
If <path> is a file and XML support has been compiled in hwloc,
|
||||
it may be a XML file exported by a previous hwloc program.
|
||||
If <path> is "\-", the standard input may be used as a XML file.
|
||||
|
||||
On Linux, <path> may be a directory containing the topology files
|
||||
gathered from another machine topology with hwloc-gather-topology.
|
||||
|
||||
On x86, <path> may be a directory containing a cpuid dump gathered
|
||||
with hwloc-gather-cpuid.
|
||||
|
||||
When the archivemount program is available, <path> may also be a tarball
|
||||
containing such Linux or x86 topology files.
|

.TP
|
||||
\fB\-i\fR <specification>, \fB\-\-input\fR <specification>
|

.TP
|
||||
\fB\-\-if\fR <format>, \fB\-\-input\-format\fR <format>
|

\fBcpuid\fR and \fBsynthetic\fR.
|
||||
.TP
|

\fB\-\-to\fR <type>
|
||||
Distribute down to objects of the given type instead of down to the bottom of
|
||||
the topology hierarchy, i.e. ignoring the structure given by objects below.
|
||||
This may be useful if some latitude is desired for the binding, e.g. just bind
|

Flags may be given as numeric values or as a comma-separated list of flag names
|
||||
that are passed to \fIhwloc_topology_restrict()\fR.
|
||||
Those names may be substrings of actual flag names as long as a single one matches,
|

.SH DESCRIPTION
|
||||
.
|
||||
hwloc-distrib generates a series of CPU masks corresponding to a distribution of
|
||||
a given number of elements over the topology of the machine. The distribution
|
||||
is done recursively from the top of the hierarchy (or from the level specified
|
||||
by option \fB\-\-from\fR) down to the bottom of the hierarchy (or down to the
|
||||
level specified by option \fB\-\-to\fR, or until only one element remains),
|
||||
splitting the number of elements at each encountered hierarchy level not ignored
|
||||
by options \fB\-\-ignore\fR.
|
||||
.
|
||||
.PP
|
||||
This can e.g. be used to distribute a set of processes hierarchically according
|
||||
to the topology of a machine. These masks can be used with hwloc-bind(1).
|
||||
.
|
||||
.PP
|
||||
.B NOTE:
|
||||
It is highly recommended that you read the hwloc(7) overview page
|
||||
before reading this man page. Most of the concepts described in
|
||||
hwloc(7) directly apply to the hwloc-bind utility.
|
||||

|
||||
.SH EXAMPLES
|
||||
.PP
|
||||
hwloc-distrib's operation is best described through several examples.
|
||||
.
|
||||
.PP
|
||||
If 4 processes have to be distributed across a machine, their CPU masks
|
||||
may be obtained with:
|
||||
|
||||
$ hwloc-distrib 4
|
||||
0x0000000f
|
||||
0x00000f00
|
||||
0x000000f0
|
||||
0x0000f000
|
||||
|
||||
To distribute only among the second package, the topology should be restricted:
|
||||
|
||||
$ hwloc-distrib --restrict $(hwloc-calc package:1) 4
|
||||
0x00000010
|
||||
0x00000020
|
||||
0x00000040
|
||||
0x00000080
|
||||
|
||||
To get a single processor of each CPU masks (prevent migration in case
|
||||
of binding)
|
||||
|
||||
$ hwloc-distrib 4 --single
|
||||
0x00000001
|
||||
0x00000100
|
||||
0x00000010
|
||||
0x00001000
|
||||
|
||||
Each output line may be converted independently with hwloc-calc:
|
||||
|
||||
$ hwloc-distrib 4 --single | hwloc-calc --taskset
|
||||
0x1
|
||||
0x100
|
||||
0x10
|
||||
0x1000
|
||||
|
||||
To convert the output into a list of processors that may be passed to
|
||||
dplace -c inside a mpirun command line:
|
||||
|
||||
$ hwloc-distrib 4 --single | xargs hwloc-calc --pulist
|
||||
0,8,4,16

.SH DESCRIPTION
|
||||
.
|
||||
hwloc-info displays information about the specified object.
|
||||
It is intended to be used with tools such as grep for filtering
|
||||
certain attribute lines.
|
||||
When no object is specified, or when \fB\-\-topology\fR is passed,
|
||||
hwloc-info prints a summary of the topology.
|
||||
When \fB\-\-support\fR is passed, hwloc-info lists the supported
|
||||
features for the topology.
|
||||
.
|
||||
.PP
|
||||
Objects may be specified as location tuples, as explained in hwloc(7).
|
||||
However hexadecimal bitmasks are not accepted since they may correspond
|
||||
to multiple objects.
|
||||
.
|
||||
.PP
|
||||
.B NOTE:
|
||||
It is highly recommended that you read the hwloc(7) overview page
|
||||
before reading this man page. Most of the concepts described in
|
||||
hwloc(7) directly apply to the hwloc-calc utility.

||||
See the OUTPUT FORMATS section below.
|
||||
.TP
|
||||
\fB\-i\fR <path>, \fB\-\-input\fR <path>
|
||||
Read the topology from <path> instead of discovering the topology of the local machine.
|
||||
|
||||
If <path> is a file and XML support has been compiled in hwloc,
|
||||
it may be a XML file exported by a previous hwloc program.
|
||||
If <path> is "\-", the standard input may be used as a XML file.
|
||||
|
||||
On Linux, <path> may be a directory containing the topology files
|
||||
gathered from another machine topology with hwloc-gather-topology.
|
||||
|
||||
On x86, <path> may be a directory containing a cpuid dump gathered
|
||||
with hwloc-gather-cpuid.
|
||||
|
||||
When the archivemount program is available, <path> may also be a tarball
|
||||
containing such Linux or x86 topology files.
|
||||
.TP
|
||||
\fB\-i\fR <specification>, \fB\-\-input\fR <specification>
|
||||
Simulate a fake hierarchy (instead of discovering the topology on the
|
||||
local machine). If <specification> is "node:2 pu:3", the topology will
|
||||
contain two NUMA nodes with 3 processing units in each of them.
|
||||
The <specification> string must end with a number of PUs.
|

\fB\-\-if\fR <format>, \fB\-\-input\-format\fR <format>
|
||||
Enforce the input in the given format, among \fBxml\fR, \fBfsroot\fR,

Enforce flags when exporting to the XML format.
|
||||
Flags may be given as numeric values or as a comma-separated list of flag names
|
||||
that are passed to \fIhwloc_topology_export_xml()\fR.
|
||||
Those names may be substrings of actual flag names as long as a single one matches.
|
||||
A value of \fB1\fR (or \fBv1\fR) reverts to the format of hwloc v1.x.
|
||||
The default is \fB0\fR (or \fBnone\fR).
|
||||
.TP
|

Only display distance matrices.
|
||||
.TP
|
||||
\fB\-\-distances-transform\fR <links|merge-switch-ports|transitive-closure>
|
||||
Try applying a transformation to distances structures before displaying them.
|
||||
See hwloc_distances_transform() for details.
|
||||
More transformations may be applied using hwloc-annotate(1)
|
||||
(and it may save their output to XML).
|
||||
.TP
|
||||
\fB\-\-memattrs\fR
|
||||
Only display memory attributes.
|
||||
All of them are displayed (while the default textual output selects
|
||||
memory attribute details depending on the verbosity level).
|
||||
.TP
|
||||
\fB\-\-cpukinds\fR
|
||||
Only display CPU kinds.
|

CPU kinds are displayed in order, starting from the most energy efficient
|
||||
ones up to the rather higher performance and power hungry ones.
|
||||
.TP
|
||||
\fB\-\-windows\-processor\-groups\fR
|

\fB\-f\fR \fB\-\-force\fR
|
||||
If the destination file already exists, overwrite it.

.TP
|
||||
\fB\-l\fR \fB\-\-logical\fR
|
||||
Display hwloc logical indexes of all objects, with prefix "L#".
|
||||
.
|
||||
By default, both logical and physical/OS indexes are displayed for PUs and NUMA nodes,
|
||||
logical only for cores, dies and packages, and no index for other types.
|
||||
.TP
|
||||
\fB\-p\fR \fB\-\-physical\fR
|
||||
Display OS/physical indexes of all objects, with prefix "P#".
|

\fB\-\-os\-index\-prefix\fR <prefix>
|
||||
Replace " P#" with the given prefix for physical/OS indexes.

\fB\-c\fR \fB\-\-cpuset\fR
|
||||
Display the cpuset of each object.
|
||||
.TP
|

\fB\-C\fR \fB\-\-cpuset\-only\fR
|
||||
Only display the cpuset of each object; do not display anything else
|
||||
about the object.
|
||||
.TP
|
||||
\fB\-\-taskset\fR
|
||||
Show CPU set strings in the format recognized by the taskset command-line
|
||||
program instead of hwloc-specific CPU set string format.
|
||||
This option should be combined with \fB\-\-cpuset\fR or \fB\-\-cpuset\-only\fR,
|
||||
otherwise it will imply \fB\-\-cpuset\fR.
|
||||
.TP
|
||||
\fB\-\-only\fR <type>
|
||||
Only show objects of the given type in the textual output.
|
||||
.TP
|
||||
\fB\-\-filter\fR <type>:<kind>, \fB\-\-filter\fR <type>
|
||||
Filter objects of type <type>, or of any type if <type> is "all".
|
||||
"io", "cache" and "icache" are also supported.
|
||||
|
||||
<kind> specifies the filtering behavior.
|
||||
If "none" or not specified, all objects of the given type are removed.
|
||||
If "all", all objects are kept as usual.
|
||||
If "structure", objects are kept when they bring structure to the topology.
|
||||
If "important" (only applicable to I/O), only important objects are kept.
|
||||
See hwloc_topology_set_type_filter() for more details.
|
||||
|
||||
hwloc supports filtering any type except PUs and NUMA nodes.
|
||||
lstopo also offers PU and NUMA node filtering by hiding them in the graphical and textual outputs,
|
||||
but any object included in them (for instance Misc) will be hidden as well.
|
||||
Note that PUs and NUMA nodes may not be ignored in the XML output.
|
||||
Note also that the top-level object type cannot be ignored (usually Machine or System).
|
||||
.TP
|
||||
\fB\-\-ignore\fR <type>
|
||||
This is the old way to specify \fB-\-filter <type>:none\fR.
|
||||
.TP
|
||||
\fB\-\-no\-smt\fR
|
||||
Ignore PUs.
|
||||
This is identical to \fB-\-filter PU:none\fR.
|
||||
.TP
|
||||
\fB\-\-no\-caches\fR
|
||||
Do not show caches.
|
||||
This is identical to \fB-\-filter cache:none\fR.
|
||||
.TP
|
||||
\fB\-\-no\-useless\-caches\fR
|
||||
This is identical to \fB-\-filter cache:structure\fR.
|

\fB\-\-no\-icaches\fR
|
||||
This is identical to \fB-\-filter icache:none\fR.
|
||||
.TP
|
||||
\fB\-\-disallowed\fR
|
||||
Include objects disallowed by administrative limitations (e.g Cgroups on Linux).
|
||||
Offline PUs and NUMA nodes are still ignored.
|
||||
.TP
|
||||
\fB\-\-allow\fR <all|local|0xff|nodeset=0xf0>
|
||||
Include objects disallowed by administrative limitations (implies \fB\-\-disallowed\fR)
|
||||
and also change the set of allowed ones.
|
||||
|
||||
If \fBlocal\fR is given, only objects available to the current process are allowed
|
||||
(default behavior when loading from the native operating system backend).
|
||||
It may be useful if the topology was created by another process (with different
|
||||
administrative restrictions such as Linux Cgroups) and loaded here loaded from XML
|
||||
or synthetic.
|
||||
This case implies \fB\-\-thissystem\fR.
|
||||
|
||||
If \fBall\fR, all objects are allowed.
|
||||
|
||||
If a bitmap is given as a hexadecimal string, it is used as the set of allowed PUs.
|
||||
|
||||
If a bitmap is given after prefix \fBnodeset=\fR, it is the set of allowed NUMA nodes.
|
||||
.TP
|
||||
\fB\-\-flags\fR <flags>
|
||||
Enforce topology flags.
|
||||
Flags may be given as numeric values or as a comma-separated list of flag names
|
||||
that are passed to \fIhwloc_topology_set_flags()\fR.
|
||||
Those names may be substrings of actual flag names as long as a single one matches,
|
||||
for instance \fBdisallowed,thissystem_allowed\fR.
|
||||
The default is \fB8\fR (or \fBimport\fR).
|
||||
.TP
|
||||
\fB\-\-merge\fR
|
||||
Do not show levels that do not have a hierarchical impact.
|
||||
This sets HWLOC_TYPE_FILTER_KEEP_STRUCTURE for all object types.
|
||||
This is identical to \fB\-\-filter all:structure\fR.
|
||||
.TP
|
||||
\fB\-\-no\-factorize\fR \fB\-\-no\-factorize\fR=<type>
|
||||
Never factorize identical objects in the graphical output.
|
||||
|
||||
If an object type is given, only factorizing of these objects is disabled.
|
||||
This only applies to normal CPU-side objects, it is independent from PCI collapsing.
|
||||
.TP
|
||||
\fB\-\-factorize\fR \fB\-\-factorize\fR=[<type>,]<N>[,<L>[,<F>]
|
||||
Factorize identical children in the graphical output (enabled by default).
|
||||
|
||||
If <N> is specified (4 by default), factorizing only occurs when there are strictly
|
||||
more than N identical children.
|
||||
If <L> and <F> are specified, they set the numbers of first and last children to keep
|
||||
after factorizing.
|
||||
|
||||
If an object type is given, only factorizing of these objects is configured.
|
||||
This only applies to normal CPU-side object, it is independent from PCI collapsing.
|
||||
.TP
|
||||
\fB\-\-no\-collapse\fR
|
||||
Do not collapse identical PCI devices.
|
||||
By default, identical sibling PCI devices (such as many virtual functions
|
||||
inside a single physical device) are collapsed.
|
||||
.TP
|
||||
\fB\-\-no\-cpukinds\fR
|
||||
Do not show different kinds of CPUs in the graphical output.
|
||||
By default, when supported, different types of lines, thickness
|
||||
and bold font may be used to display PU boxes of different kinds.
|
||||
.TP
|
||||
\fB\-\-restrict\fR <cpuset>
|

Restrict the topology to the given cpuset.
|
||||
.TP
|

\fB\-\-restrict\fR nodeset=<nodeset>
|
||||
Restrict the topology to the given nodeset, unless --restrict-flags specifies something different.
|
||||
.TP
|
||||
\fB\-\-restrict\fR binding
|
||||
Restrict the topology to the current process binding.
|
||||
This option requires the use of the actual current machine topology
|
||||
(or any other topology with \fB\-\-thissystem\fR or with
|
||||
HWLOC_THISSYSTEM set to 1 in the environment).
|
||||
.TP
|
||||
\fB\-\-restrict\-flags\fR <flags>
|
||||
Enforce flags when restricting the topology.
|
||||
Flags may be given as numeric values or as a comma-separated list of flag names
|
||||
that are passed to \fIhwloc_topology_restrict()\fR.
|
||||
Those names may be substrings of actual flag names as long as a single one matches,
|
||||
for instance \fBbynodeset,memless\fR.
|
||||
The default is \fB0\fR (or \fBnone\fR).
|
||||
.TP
|
||||
\fB\-\-no\-io\fB
|
||||
Do not show any I/O device or bridge.
|
||||
This is identical to \fB\-\-filter io:none\fR.
|
||||
By default, common devices (GPUs, NICs, block devices, ...) and
|
||||
interesting bridges/switches are shown.
|
||||
.TP
|
||||
\fB\-\-no\-bridges\fB
|
||||
Do not show any I/O bridge except hostbridges.
|

\fB\-\-thissystem\fR
|
||||
Assume that the selected backend provides the topology for the
|

and using \fB\-\-restrict binding\fR or \fB\-\-allow all\fR.
|
||||
.TP
|
||||
\fB\-\-pid\fR <pid>
|
||||
Detect topology as seen by process <pid>, i.e. as if process <pid> did the
|
||||
discovery itself.
|
||||
Note that this can for instance change the set of allowed processors.
|
||||
Also show this process current CPU and Memory binding by marking the corresponding
|
||||
PUs and NUMA nodes (in Green in the graphical output, see the COLORS section below,
|
||||
or by appending \fI(binding)\fR to the verbose text output).
|
||||
If 0 is given as pid, the current binding for the lstopo process will be shown.
|
||||
.TP
|
||||
\fB\-\-ps\fR \fB\-\-top\fR
|
||||
Show existing processes as misc objects in the output. To avoid uselessly
|
||||
cluttering the output, only processes that are restricted to some part of the
|
||||
machine are shown. On Linux, kernel threads are not shown.
|
||||
If many processes appear, the output may become hard to read anyway,
|
||||
making the hwloc-ps program more practical.
|
||||
.TP
|
||||
\fB\-\-children\-order\fR <order>
|
||||
Change the order of the different kinds of children with respect to
|
||||
their parent in the graphical output.
|
||||
\fI<order>\fR may be a comma-separated list of keywords among:
|
||||
|
||||
\fImemory:above\fR displays memory children above other children
|
||||
(and above the parent if it is a cache).
|
||||
PUs are therefore below their local NUMA nodes, like hwloc 1.x did.
|
||||
|
||||
\fIio:right\fR and \fImisc:right\fR place I/O or Misc children
|
||||
on the right of CPU children.
|
||||
|
||||
\fIio:below\fR and \fImisc:below\fR place I/O or Misc children
|
||||
below CPU children.
|
||||
|
||||
\fIplain\fR places everything not specified together with
|
||||
normal CPU children.
|
||||
|
||||
If only \fIplain\fR is specified, lstopo displays the topology
|
||||
in a basic manner that strictly matches the actual tree:
|
||||
Memory, I/O and Misc children are listed below their parent just like any other child.
|
||||
PUs are therefore on the side of their local NUMA nodes,
|
||||
below a common ancestor.
|
||||
This output may result in strange layouts since the size of Memory,
|
||||
CPU and I/O children may be very different, causing the placement
|
||||
algorithm to poorly arrange them in rows.
|
||||
|
||||
The default order is \fImemory:above,io:right,misc:right\fR which means
|
||||
Memory children are above CPU children while I/O and Misc are together
|
||||
on the right.
|
||||
|
||||
Up to hwloc 2.5, the default was rather to \fImemory:above,plain\fR.
|
||||
|
||||
Additionally, \fIio:right\fR, \fIio:below\fR, \fImisc:right\fR
|
||||
and \fImisc:below\fR may be suffixed with
|
||||
\fI:horiz\fR, \fI:vert\fR or \fI:rect\fR to force the horizontal,
|
||||
vertical or rectangular layout of children inside these sections.

.SH DESCRIPTION
|
||||
.
|
||||
lstopo and lstopo-no-graphics are capable of displaying a topological map of
|
||||
the system in a variety of different output formats. The only difference
|
||||
between lstopo and lstopo-no-graphics is that graphical outputs are only
|
||||
supported by lstopo, to reduce dependencies on external libraries.
|
||||
hwloc-ls is identical to lstopo-no-graphics.
|
||||
.
|
||||
.PP
|
||||
The filename specified directly implies the output format that will be
|
||||
used; see the OUTPUT FORMATS section, below. Output formats that
|
||||
support color will indicate specific characteristics about individual
|
||||
CPUs by their color; see the COLORS section, below.

.SH OUTPUT FORMATS
|

.
|
||||
.PP
|
||||
By default, if no output filename is specific, the output is sent
|
||||
to a graphical window if possible in the current environment
|
||||
(DISPLAY environment variable set on Unix, etc.).
|
||||
Otherwise, a text summary is displayed in the console.
|
||||
The console is also used when the program runs from a terminal
|
||||
and the output is redirected to a pipe or file.
|
||||
These default behaviors may be changed by passing \fB\-\-of console\fR
|
||||
to force console mode or \fB\-\-of window\fR for graphical window.
|
||||
.
|
||||
.PP
|
||||
The filename on the command line usually determines the format of the output.
|
||||
There are a few filenames that indicate specific output formats and
|
||||
devices (e.g., a filename of "-" will output a text summary to
|
||||
stdout), but most filenames indicate the desired output format by
|
||||
their suffix (e.g., "topo.png" will output a PNG-format file).
|
||||
.PP
|
||||
The format of the output may also be changed with "\-\-of".
|
||||
For instance, "\-\-of pdf" will generate a PDF-format file on the standard
|
||||
output, while "\-\-of fig toto" will output a Xfig-format file named "toto".
|
||||
.
|
||||

|
||||
The list of currently supported formats is given below. Any of them may
|
||||
be used with "\-\-of" or as a filename suffix.

|

.
|
||||
.SH GRAPHICAL OUTPUT
|
||||
The graphical output is made of nested boxes representing
|
||||
the inclusion of objects in the hierarchy of resources.
|
||||
Usually a Machine box contains one or several Package boxes,
|
||||
that contain multiple Core boxes, with one or several PUs each.
|
||||
|
||||
.SS Caches
|
||||
Caches are displayed in a slightly different manner because
|
||||
they do not actually include computing resources such as cores.
|
||||
For instance, a L2 Cache shared by a pair of Cores is drawn
|
||||
as a Cache box on top of two Core boxes
|
||||
(instead of having Core boxes inside the Cache box).
|
||||
|
||||
.SS NUMA nodes and Memory-side Caches
|
||||
By default, NUMA nodes boxes are drawn on top of their local
|
||||
computing resources.
|
||||
For instance, a processor Package containing one NUMA node
|
||||
and four Cores is displayed as a Package box containing
|
||||
the NUMA node box above four Core boxes.
|
||||
If a NUMA node is local to the L3 Cache, the NUMA node is displayed
|
||||
above that Cache box.
|
||||
All this specific drawing strategy for memory objects may be disabled
|
||||
by passing command-line option \fB\-\-children\-order plain\fR.
|
||||
|
||||
If multiple NUMA nodes are attached to the same parent object,
|
||||
they are displayed inside an additional unnamed memory box.
|
||||
|
||||
If some Memory-side Caches exist in front of some NUMA nodes,
|
||||
they are drawn as boxes immediately above them.
|
||||
|
||||
.SS PCI bridges, PCI devices and OS devices
|
||||
The PCI hierarchy is not drawn as a set of included boxes but rather
|
||||
as a tree of bridges (that may actually be switches) with links between them.
|
||||
The tree starts with a small square on the left for the
|
||||
hostbridge or root complex.
|
||||
It ends with PCI device boxes on the right.
|
||||
Intermediate PCI bridges/switches may appear as additional small
|
||||
squares in the middle.
|
||||
|
||||
PCI devices on the right of the tree are boxes containing
|
||||
their PCI bus ID (such as 00:02.3).
|
||||
They may also contain sub-boxes for OS device objects
|
||||
such as a network interface \fIeth0\fR or a CUDA GPU \fIcuda0\fR.
|
||||
|
||||
When there is a single link (horizontal line) on the right of a
|
||||
PCI bridge, it means that a single device or bridge is connected
|
||||
on the secondary PCI bus behind that bridge.
|
||||
When there is a vertical line, it means that multiple devices
|
||||
and/or bridges are connected to the same secondary PCI bus.
|
||||
|
||||
The datarate of a PCI link may be written (in GB/s) right below
|
||||
its drawn line (if the operating system and/or libraries are able
|
||||
to report that information).
|
||||
This datarate is the currently configured speed of the entire PCI link
|
||||
(sum of the bandwidth of all PCI lanes in that link).
|
||||
It may change during execution since some devices are able to
|
||||
slow their PCI links down when idle.

.\" Layout Section

.\" **************************
|
||||
.SH LAYOUT
|
||||
In its graphical output, lstopo uses simple rectangular heuristics
|
||||
to try to achieve a 4/3 ratio between width and height.
|
||||
Although the hierarchy of resources is properly reflected,
|
||||
the exact physical organization (NUMA distances, rings,
|
||||
complete graphs, etc.) is currently ignored.
|
||||
|
||||
The layout of a level may be changed with \fB\-\-vert\fR, \fB\-\-horiz\fR,
|
||||
and \fB\-\-rect\fR to force a parent object to arrange its children
|
||||
in vertical, horizontal or rectangular manners respectively.
|
||||
|
||||
The position of Memory, I/O and Misc children with respect to other
|
||||
children objects may be changed using \fB\-\-children\-order\fR.
|
||||
This effectivement divides children into multiple sections.
|
||||
The layout of children is first computed inside each section,
|
||||
before sections are placed inside (or below) the parent box.
|
||||
|
||||
The vertical/horizontal/rectangular layout of these additional
|
||||
sections may also be configured through \fB\-\-children\-order\fR.

The CPU or NUMA node is in the allowed set (see below).

|

The "allowed set" is the set of CPUs or NUMA nodes to which the current process is
|
||||
allowed to bind. The allowed set is usually either inherited from the
|
||||
parent process or set by administrative qpolicies on the system. Linux
|
||||
cpusets are one example of limiting the allowed set for a process and
|
||||
its children to be less than the full set of CPUs or NUMA nodes on the system.
|
||||
.PP
|
||||
Different processes may therefore have different CPUs or NUMA nodes in the allowed
|
||||
set. Hence, invoking lstopo in different contexts and/or as different
|
||||
users may display different colors for the same individual CPUs (e.g.,
|
||||
running lstopo in one context may show a specific CPU as red, but
|
||||
running lstopo in a different context may show the same CPU as white).
|
||||
.PP
|
||||
Some lstopo output modes, e.g. the console mode (default non-graphical output),
|
||||
do not support colors at all.
|
||||
The console mode displays the above characteristics by appending text
|
||||
to each PU line if verbose messages are enabled.
|
||||
.
|
||||
.SH CUSTOM COLORS
|
||||
The colors of different kinds of boxes may be configured with \fB\-\-palette\fR.
|
||||
|
||||
The color of each object in the graphical output may also be enforced by
|
||||
specifying a "lstopoStyle" info attribute in that object.
|
||||
Its value should be a semi-colon separated list of "<attribute>=#rrggbb"
|
||||
where rr, gg and bb are the RGB components of a color,
|
||||
each between 0 and 255, in hexadecimal (00 to ff).
|
||||
.
|
||||
<attribute> may be

|

\fBBackground\fR

\fBText\fR
|
||||
Sets the color of the text showing the object name, type, index, etc.
|

.TP
|
||||
\fBText2\fB
|
||||
Sets the color of the additional text near the object,
|
||||
for instance the link speed behind a PCI bridge.
|
||||
.PP
|
||||
The "lstopoStyle" info may be added to a temporarily-saved XML topologies
|
||||
with hwloc-annotate, or with hwloc_obj_add_info().
|
||||
.
|
||||
For instance, to display all core objects in blue (with white names):
|
||||
|
||||
lstopo save.xml
|
||||
hwloc-annotate save.xml save.xml core:all info lstopoStyle "Background=#0000ff;Text=#ffffff"
|

|

.SH DESCRIPTION
|
||||
.
|
||||
hwloc-patch loads the difference between two topologies from a XML file
|
||||
(or from the standard input) and applies it to an
|
||||
existing topology, generating a new, modified one.
|
||||
.
|
||||
.PP
|
||||
The XML difference may have been computed earlier with hwloc-diff
|
||||
or hwloc-compress-dir.
|
||||
.
|
||||
.PP
|
||||
If <output.xml> is given, the new, modified topology is stored in that
|
||||
new file. Otherwise, <topology.xml> is modified in place.
|
||||
.
|
||||
.PP
|
||||
If \fBrefname\fR is given instead of <topology.xml>, the input topology filename
|
||||
is automatically guessed by reading the refname field of the XML diff file.
|
||||
By default hwloc-diff generates XML diffs with the right reference topology
|
||||
filename (without any path prefix).
|
||||
.
|
||||
.PP
|
||||
If \fB-\fR is given instead of <diff.xml>, the topology difference is read from
|
||||
the standard input.
|
||||
.
|
||||
.PP
|
||||
.B NOTE:
|
||||
If some application-specific userdata were been exported to the input XMLs,
|
||||
they will be ignored and discarded from the output because hwloc has no way
|
||||
to understand and patch them.
|
||||
.
|
||||
.PP
|
||||
.B NOTE:
|
||||
It is highly recommended that you read the hwloc(7) overview page
|
||||
before reading this man page. Most of the concepts described in
|
||||
hwloc(7) directly apply to the hwloc-patch utility.

hwloc-patch's operation is best described through several examples.
|
||||
.
|
||||
.PP
|
||||
Apply a XML topology difference file to an existing topology:
|
||||
|
||||
$ hwloc-patch fourmi023.xml diff.xml fourmi023-new.xml
|
||||
|
||||
Apply a XML topology difference file whole refname field contains the right input topology:
|
||||
|
||||
$ hwloc-patch refname diff.xml fourmi023-new.xml
|
||||
|
||||
Apply a XML topology from the standard intput:
|
||||
|
||||
$ cat diff.xml | hwloc-patch fourmi023.xml - fourmi023-new.xml
|
||||
|
||||
Directly compute the difference between two topologies and apply it
|
||||
to another one, in place:
|
||||
|
||||
$ hwloc-diff fourmi023.xml fourmi024.xml | hwloc-patch fourmi025.xml -

.SH RETURN VALUE
|
||||
Upon successful execution, hwloc-patch outputs the modified topology.
|
||||
The return value is 0.
|
||||
.
|
||||
.PP
|
||||
hwloc-patch also returns nonzero if any kind of error occurs, such as

If \fBlocal\fR is given, only objects available to the current process are allowed
|

(default behavior when loading from the native operating system backend).
|

It may be useful if the topology was created by another process (with different

or synthetic.
|

If an object type is given, only factorizing of these objects is disabled.
|

\fB\-\-factorize\fR \fB\-\-factorize\fR=[<type>,]<N>[,<L>[,<F>]
|

Factorize identical children in the graphical output (enabled by default).
|

If <N> is specified (4 by default), factorizing only occurs when there are strictly
|

more than N identical children.
|

If <L> and <F> are specified, they set the numbers of first and last children to keep
|

\fB\-\-no\-cpukinds\fR
|

.TP
|

\fB\-\-restrict\fR binding
|

This option requires the use of the actual current machine topology

(or any other topology with \fB\-\-thissystem\fR or with
|
||||
HWLOC_THISSYSTEM set to 1 in the environment).
|
||||
.TP
|

\fB\-\-restrict\-flags\fR <flags>
|

Enforce flags when restricting the topology.
|

Flags may be given as numeric values or as a comma-separated list of flag names
|
||||
that are passed to \fIhwloc_topology_restrict()\fR.
|

Those names may be substrings of actual flag names as long as a single one matches,

\fB\-\-no\-bridges\fB
|

interesting bridges/switches are shown.
|

By default, only common devices (GPUs, NICs, block devices, ...) and
|

interesting bridges/switches are shown.
|
||||
.TP
|
||||
\fB\-\-thissystem\fR
|
||||
Assume that the selected backend provides the topology for the
|
||||
system on which we are running.
|
||||
This is useful when loading a custom topology such as an XML file
|
||||
and using \fB\-\-restrict binding\fR or \fB\-\-allow all\fR.
|
||||
.TP
|
||||
\fB\-\-pid\fR <pid>
|
||||
Detect topology as seen by process <pid>, i.e. as if process <pid> did the
|
||||
discovery itself.
|
||||
Note that this can for instance change the set of allowed processors.
|
||||
Also show this process current CPU and Memory binding by marking the corresponding
|
||||
PUs and NUMA nodes (in Green in the graphical output, see the COLORS section below,
|
||||
or by appending \fI(binding)\fR to the verbose text output).
|
||||
If 0 is given as pid, the current binding for the lstopo process will be shown.
|
||||
.TP
|
||||
\fB\-\-ps\fR \fB\-\-top\fR
|
||||
Show existing processes as misc objects in the output. To avoid uselessly
|
||||
cluttering the output, only processes that are restricted to some part of the
|
||||
machine are shown. On Linux, kernel threads are not shown.
|
||||
If many processes appear, the output may become hard to read anyway,
|
||||
making the hwloc-ps program more practical.
|
||||
.TP
|
||||
\fB\-\-children\-order\fR <order>
|
||||
Change the order of the different kinds of children with respect to
|
||||
their parent in the graphical output.
|
||||
\fI<order>\fR may be a comma-separated list of keywords among:
|
||||
|
||||
\fImemory:above\fR displays memory children above other children
|
||||
(and above the parent if it is a cache).
|
||||
PUs are therefore below their local NUMA nodes, like hwloc 1.x did.
|
||||
|
||||
\fIio:right\fR and \fImisc:right\fR place I/O or Misc children
|
||||
on the right of CPU children.
|
||||
|
||||
\fIio:below\fR and \fImisc:below\fR place I/O or Misc children
|
||||
below CPU children.
|
||||
|
||||
\fIplain\fR places everything not specified together with
|
||||
normal CPU children.
|
||||
|
||||
If only \fIplain\fR is specified, lstopo displays the topology
|
||||
in a basic manner that strictly matches the actual tree:
|
||||
Memory, I/O and Misc children are listed below their parent just like any other child.
|
||||
PUs are therefore on the side of their local NUMA nodes,
|
||||
below a common ancestor.
|
||||
This output may result in strange layouts since the size of Memory,
|
||||
CPU and I/O children may be very different, causing the placement
|
||||
algorithm to poorly arrange them in rows.
|
||||
|
||||
The default order is \fImemory:above,io:right,misc:right\fR which means
|
||||
Memory children are above CPU children while I/O and Misc are together
|
||||
on the right.
|
||||
|
||||
Up to hwloc 2.5, the default was rather to \fImemory:above,plain\fR.
|
||||
|
||||
Additionally, \fIio:right\fR, \fIio:below\fR, \fImisc:right\fR
|
||||
and \fImisc:below\fR may be suffixed with
|
||||
\fI:horiz\fR, \fI:vert\fR or \fI:rect\fR to force the horizontal,
|
||||
vertical or rectangular layout of children inside these sections.

The \fILSTOPO_TEXT_XSCALE\fR environment variable may be used
|

.SH DESCRIPTION
|
||||
.
|
||||
lstopo and lstopo-no-graphics are capable of displaying a topological map of
|
||||
the system in a variety of different output formats. The only difference
|
||||
between lstopo and lstopo-no-graphics is that graphical outputs are only
|
||||
supported by lstopo, to reduce dependencies on external libraries.
|
||||
hwloc-ls is identical to lstopo-no-graphics.
|
||||
.
|
||||
.PP
|
||||
The filename specified directly implies the output format that will be
|
||||
used; see the OUTPUT FORMATS section, below. Output formats that
|
||||
support color will indicate specific characteristics about individual
|
||||
CPUs by their color; see the COLORS section, below.

.SH OUTPUT FORMATS
|
||||
.
|
||||
.PP
|
||||
By default, if no output filename is specific, the output is sent
|
||||
to a graphical window if possible in the current environment
|
||||
(DISPLAY environment variable set on Unix, etc.).
|
||||
Otherwise, a text summary is displayed in the console.
|
||||
The console is also used when the program runs from a terminal
|
||||
and the output is redirected to a pipe or file.
|
||||
These default behaviors may be changed by passing \fB\-\-of console\fR
|
||||
to force console mode or \fB\-\-of window\fR for graphical window.
|
||||
.
|
||||
.PP
|
||||
The filename on the command line usually determines the format of the output.
|
||||
There are a few filenames that indicate specific output formats and
|
||||
devices (e.g., a filename of "-" will output a text summary to
|
||||
stdout), but most filenames indicate the desired output format by
|
||||
their suffix (e.g., "topo.png" will output a PNG-format file).
|
||||
.PP
|
||||
The format of the output may also be changed with "\-\-of".
|
||||
For instance, "\-\-of pdf" will generate a PDF-format file on the standard
|
||||
output, while "\-\-of fig toto" will output a Xfig-format file named "toto".
|
||||
.
|
||||
.PP
|
||||
The list of currently supported formats is given below. Any of them may
|
||||
be used with "\-\-of" or as a filename suffix.
|
||||
.TP
|
||||
.B default
|
||||
Send the output to a window or to the console depending on the environment.
|
||||

.B window
|
||||
Send the output to a graphical window.
|
||||
.
|
||||
.TP
|
||||
.B console
|
||||
Send a text summary to stdout.
|

Binding or unallowed processors are only annotated in this mode
|
||||
if verbose; see the COLORS section, below.
|
||||
.
|
||||
.TP
|
||||
.B ascii
|
||||
Output an ASCII art representation of the map
|
||||
(formerly called \fBtxt\fR).
|

If outputting to stdout and if colors are supported on the terminal,
|
||||
the output will be colorized.

.B svg
|
||||
Output a SVG representation of the map,
|
||||
using Cairo (by default, if supported)
|
||||
or a native SVG backend (fallback, always supported).
|

.
|
||||
.TP
|
||||
\fBnativesvg\fR or \fBsvg(native)\fR
|
||||
Output a SVG representation of the map using the native SVG backend.
|
||||
It may be less pretty than the Cairo output, but it is always supported,
|
||||
and SVG objects have attributes for identifying and manipulating them.
|
||||

lstopo outputs a synthetic description string.
|
||||
This output may be reused as an input synthetic topology

|
||||
.
|
||||
.SH GRAPHICAL OUTPUT
|
||||
The graphical output is made of nested boxes representing
|
||||
the inclusion of objects in the hierarchy of resources.
|
||||
Usually a Machine box contains one or several Package boxes,
|
||||
that contain multiple Core boxes, with one or several PUs each.
|
||||
|
||||
.SS Caches
|
||||
Caches are displayed in a slightly different manner because
|
||||
they do not actually include computing resources such as cores.
|
||||
For instance, a L2 Cache shared by a pair of Cores is drawn
|
||||
as a Cache box on top of two Core boxes
|
||||
(instead of having Core boxes inside the Cache box).
|
||||
|
||||
.SS NUMA nodes and Memory-side Caches
|
||||
By default, NUMA nodes boxes are drawn on top of their local
|
||||
computing resources.
|
||||
For instance, a processor Package containing one NUMA node
|
||||
and four Cores is displayed as a Package box containing
|
||||
the NUMA node box above four Core boxes.
|
||||
If a NUMA node is local to the L3 Cache, the NUMA node is displayed
|
||||
above that Cache box.
|
||||
All this specific drawing strategy for memory objects may be disabled
|
||||
by passing command-line option \fB\-\-children\-order plain\fR.
|
||||
|
||||
If multiple NUMA nodes are attached to the same parent object,
|
||||
they are displayed inside an additional unnamed memory box.
|
||||
|
||||
If some Memory-side Caches exist in front of some NUMA nodes,
|
||||
they are drawn as boxes immediately above them.
|
||||
|
||||
.SS PCI bridges, PCI devices and OS devices
|
||||
The PCI hierarchy is not drawn as a set of included boxes but rather
|
||||
as a tree of bridges (that may actually be switches) with links between them.
|
||||
The tree starts with a small square on the left for the
|
||||
hostbridge or root complex.
|
||||
It ends with PCI device boxes on the right.
|
||||
Intermediate PCI bridges/switches may appear as additional small
|
||||
squares in the middle.
|
||||
|
||||
PCI devices on the right of the tree are boxes containing
|
||||
their PCI bus ID (such as 00:02.3).
|
||||
They may also contain sub-boxes for OS device objects
|
||||
such as a network interface \fIeth0\fR or a CUDA GPU \fIcuda0\fR.
|
||||
|
||||
When there is a single link (horizontal line) on the right of a
|
||||
PCI bridge, it means that a single device or bridge is connected
|
||||
on the secondary PCI bus behind that bridge.
|
||||
When there is a vertical line, it means that multiple devices
|
||||
and/or bridges are connected to the same secondary PCI bus.
|
||||
|
||||
The datarate of a PCI link may be written (in GB/s) right below
|
||||
its drawn line (if the operating system and/or libraries are able
|
||||
to report that information).
|
||||
This datarate is the currently configured speed of the entire PCI link
|
||||
(sum of the bandwidth of all PCI lanes in that link).
|
||||
It may change during execution since some devices are able to
|
||||
slow their PCI links down when idle.

||||

|
||||
.\" Layout Section
|
||||
.\" **************************
|
||||
.SH LAYOUT
|
||||
In its graphical output, lstopo uses simple rectangular heuristics
|
||||
to try to achieve a 4/3 ratio between width and height.
|
||||
Although the hierarchy of resources is properly reflected,
|
||||
the exact physical organization (NUMA distances, rings,
|
||||
complete graphs, etc.) is currently ignored.
|
||||
|
||||
The layout of a level may be changed with \fB\-\-vert\fR, \fB\-\-horiz\fR,
|
||||
and \fB\-\-rect\fR to force a parent object to arrange its children
|
||||
in vertical, horizontal or rectangular manners respectively.
|
||||
|
||||
The position of Memory, I/O and Misc children with respect to other
|
||||
children objects may be changed using \fB\-\-children\-order\fR.
|
||||
This effectivement divides children into multiple sections.
|
||||
The layout of children is first computed inside each section,
|
||||
before sections are placed inside (or below) the parent box.
|
||||
|
||||
The vertical/horizontal/rectangular layout of these additional
|
||||
sections may also be configured through \fB\-\-children\-order\fR.
|
||||
.

|

.\" Colors Section
|

.\" **************************
|
||||
.SH COLORS
|
||||
Individual CPUs and NUMA nodes are colored in the graphical output
|
||||
formats to indicate different characteristics:
|
||||
.TP
|
||||
Green
|
||||
The topology is reported as seen by a specific process (see \fB\-\-pid\fR),
|
||||
and the given CPU or NUMA node is in this process CPU or Memory binding mask.
|
||||
.TP
|
||||
White
|
||||
The CPU or NUMA node is in the allowed set (see below).
|
||||
If the topology is reported as seen by a specific process (see \fB\-\-pid\fR),
|
||||
the object is also not in this process binding mask.
|
||||
.TP
|
||||
Red
|
||||
The CPU or NUMA node is not in the allowed set (see below).
|
||||
.
|
||||
.PP
|
||||
The "allowed set" is the set of CPUs or NUMA nodes to which the current process is
|
||||
allowed to bind. The allowed set is usually either inherited from the
|
||||
parent process or set by administrative qpolicies on the system. Linux
|
||||
cpusets are one example of limiting the allowed set for a process and
|
||||
its children to be less than the full set of CPUs or NUMA nodes on the system.
|
||||
.PP
|
||||
Different processes may therefore have different CPUs or NUMA nodes in the allowed
|
||||
set. Hence, invoking lstopo in different contexts and/or as different
|
||||
users may display different colors for the same individual CPUs (e.g.,
|
||||
running lstopo in one context may show a specific CPU as red, but
|
||||
running lstopo in a different context may show the same CPU as white).
|
||||
.PP
|
||||
Some lstopo output modes, e.g. the console mode (default non-graphical output),
|
||||
do not support colors at all.
|
||||
The console mode displays the above characteristics by appending text
|
||||
to each PU line if verbose messages are enabled.
|
||||
.
|
||||
.SH CUSTOM COLORS
|
||||
The colors of different kinds of boxes may be configured with \fB\-\-palette\fR.
|
||||
|
||||
The color of each object in the graphical output may also be enforced by
|
||||
specifying a "lstopoStyle" info attribute in that object.
|
||||
Its value should be a semi-colon separated list of "<attribute>=#rrggbb"
|
||||
where rr, gg and bb are the RGB components of a color,
|
||||
each between 0 and 255, in hexadecimal (00 to ff).
|
||||
.
|
||||
<attribute> may be
|
||||
.TP
|
||||
\fBBackground\fR
|
||||
Sets the background color of the main object box.
|
||||
.TP
|
||||
\fBText\fR
|
||||
Sets the color of the text showing the object name, type, index, etc.
|
||||
.TP
|
||||
\fBText2\fB
|
||||
Sets the color of the additional text near the object,
|
||||
for instance the link speed behind a PCI bridge.
|
||||
.PP
|
||||
The "lstopoStyle" info may be added to a temporarily-saved XML topologies
|
||||
with hwloc-annotate, or with hwloc_obj_add_info().
|
||||
.
|
||||
For instance, to display all core objects in blue (with white names):
|
||||
|
||||
lstopo save.xml
|
||||
hwloc-annotate save.xml save.xml core:all info lstopoStyle "Background=#0000ff;Text=#ffffff"
|
||||
lstopo -i save.xml

|
||||
lstopo-no-graphics
|
||||
|
||||
To display the machine topology in ascii-art mode:
|
||||
|
||||
lstopo-no-graphics -.ascii
|
||||
|
||||
To display in graphical mode (assuming that the DISPLAY environment
|
||||
variable is set to a relevant value):
|
||||
|
||||
lstopo
|
||||
|
||||
To export the topology to a PNG file:
|
||||
|
||||
lstopo file.png
|
||||
|
||||
To export an XML file on a machine and later display the corresponding
|
||||
graphical output on another machine:
|
||||
|
||||
machine1$ lstopo file.xml
|
||||
<transfer file.xml from machine1 to machine2>
|
||||
machine2$ lstopo --input file.xml
|
||||
|
||||
To save the current machine topology to XML and later reload it faster
|
||||
while still considering it as the current machine:
|
||||
|
||||
$ lstopo file.xml
|
||||
<...>
|
||||
$ lstopo --input file.xml --thissystem
|
||||
|
||||
To restrict an XML topology to only physical processors 0, 1, 4 and 5:
|
||||
|
||||
lstopo --input file.xml --restrict 0x33 newfile.xml
|
||||
|
||||
To restrict an XML topology to only numa node whose logical index is 1:
|
||||
|
||||
lstopo --input file.xml --restrict $(hwloc-calc --input file.xml node:1) newfile.xml
|
||||
|
||||
To display a summary of the topology:
|
||||
|
||||
lstopo -s
|
||||
|
||||
To get more details about the topology:
|
||||
|
||||
lstopo -v
|
||||
|
||||
To only show cores:
|
||||
|
||||
lstopo --only core
|
||||
|
||||
To show cpusets:
|
||||
|
||||
lstopo --cpuset
|
||||
|
||||
To only show the cpusets of package:
|
||||
|
||||
lstopo --only package --cpuset-only
|
||||
|
||||
Simulate a fake hierarchy; this example shows with 2 NUMA nodes of 2
|
||||
processor units:
|
||||
|
||||
lstopo --input "node:2 2"
|
||||
|
||||
To count the number of logical processors in the system
|
||||
|
||||
lstopo --only pu | wc -l
|
||||
|
||||
To append the kernel release and version to the graphical legend:
|
||||
|
||||
lstopo --append-legend "Kernel release: $(uname -r)" --append-legend "Kernel version: $(uname -v)"

\fB\-\-filter\fR <type>:<kind>, \fB\-\-filter\fR <type>
|
||||
Filter objects of type <type>, or of any type if <type> is "all".
|
||||
"io", "cache" and "icache" are also supported.
|
||||
|
||||
<kind> specifies the filtering behavior.
|
||||
If "none" or not specified, all objects of the given type are removed.
|
||||
If "all", all objects are kept as usual.
|
||||
If "structure", objects are kept when they bring structure to the topology.
|

hwloc supports filtering any type except PUs and NUMA nodes.
|
||||
lstopo also offers PU and NUMA node filtering by hiding them in the graphical and textual outputs,
|
||||
but any object included in them (for instance Misc) will be hidden as well.

\fB\-\-no\-smt\fR
|
||||
Ignore PUs.
|
||||
This is identical to \fB-\-filter PU:none\fR.
|
||||
.TP
|
||||
\fB\-\-no\-caches\fR
|
||||
Do not show caches.

It may be useful if the topology was created by another process (with different

\fB\-\-factorize\fR \fB\-\-factorize\fR=[<type>,]<N>[,<L>[,<F>]
|

Factorize identical children in the graphical output (enabled by default).
|

If <N> is specified (4 by default), factorizing only occurs when there are strictly
|

more than N identical children.
|

\fB\-\-no\-cpukinds\fR
|

This option requires the use of the actual current machine topology

(or any other topology with \fB\-\-thissystem\fR or with
|
||||
HWLOC_THISSYSTEM set to 1 in the environment).
|

.TP
|

\fB\-\-restrict\-flags\fR <flags>
|

Enforce flags when restricting the topology.
|

Flags may be given as numeric values or as a comma-separated list of flag names
|
||||
that are passed to \fIhwloc_topology_restrict()\fR.
|

Those names may be substrings of actual flag names as long as a single one matches,

By default, only common devices (GPUs, NICs, block devices, ...) and
|

interesting bridges/switches are shown.
|
||||
.TP
|
||||
\fB\-\-thissystem\fR
|
||||
Assume that the selected backend provides the topology for the
|
||||
system on which we are running.
|
||||
This is useful when loading a custom topology such as an XML file
|
||||
and using \fB\-\-restrict binding\fR or \fB\-\-allow all\fR.
|
||||
.TP
|
||||
\fB\-\-pid\fR <pid>
|
||||
Detect topology as seen by process <pid>, i.e. as if process <pid> did the
|
||||
discovery itself.
|
||||
Note that this can for instance change the set of allowed processors.
|
||||
Also show this process current CPU and Memory binding by marking the corresponding
|
||||
PUs and NUMA nodes (in Green in the graphical output, see the COLORS section below,
|
||||
or by appending \fI(binding)\fR to the verbose text output).
|
||||
If 0 is given as pid, the current binding for the lstopo process will be shown.
|
||||
.TP
|
||||
\fB\-\-ps\fR \fB\-\-top\fR
|
||||
Show existing processes as misc objects in the output. To avoid uselessly
|
||||
cluttering the output, only processes that are restricted to some part of the
|
||||
machine are shown. On Linux, kernel threads are not shown.
|
||||
If many processes appear, the output may become hard to read anyway,
|
||||
making the hwloc-ps program more practical.
|
||||
.TP
|
||||
\fB\-\-children\-order\fR <order>
|
||||
Change the order of the different kinds of children with respect to
|
||||
their parent in the graphical output.
|
||||
\fI<order>\fR may be a comma-separated list of keywords among:
|
||||
|
||||
\fImemory:above\fR displays memory children above other children
|
||||
(and above the parent if it is a cache).
|
||||
PUs are therefore below their local NUMA nodes, like hwloc 1.x did.
|
||||
|
||||
\fIio:right\fR and \fImisc:right\fR place I/O or Misc children
|
||||
on the right of CPU children.
|
||||
|
||||
\fIio:below\fR and \fImisc:below\fR place I/O or Misc children
|
||||
below CPU children.
|
||||
|
||||
\fIplain\fR places everything not specified together with
|
||||
normal CPU children.
|
||||
|
||||
If only \fIplain\fR is specified, lstopo displays the topology
|
||||
in a basic manner that strictly matches the actual tree:
|
||||
Memory, I/O and Misc children are listed below their parent just like any other child.
|
||||
PUs are therefore on the side of their local NUMA nodes,
|
||||
below a common ancestor.
|
||||
This output may result in strange layouts since the size of Memory,
|
||||
CPU and I/O children may be very different, causing the placement
|
||||
algorithm to poorly arrange them in rows.
|
||||
|
||||
The default order is \fImemory:above,io:right,misc:right\fR which means
|
||||
Memory children are above CPU children while I/O and Misc are together
|
||||
on the right.
|
||||
|
||||
Up to hwloc 2.5, the default was rather to \fImemory:above,plain\fR.
|
||||
|
||||
Additionally, \fIio:right\fR, \fIio:below\fR, \fImisc:right\fR
|
||||
and \fImisc:below\fR may be suffixed with
|
||||
\fI:horiz\fR, \fI:vert\fR or \fI:rect\fR to force the horizontal,
|
||||
vertical or rectangular layout of children inside these sections.

The \fILSTOPO_TEXT_XSCALE\fR environment variable may be used
|

.SH DESCRIPTION
|
||||
.
|
||||
lstopo and lstopo-no-graphics are capable of displaying a topological map of
|
||||
the system in a variety of different output formats. The only difference
|
||||
between lstopo and lstopo-no-graphics is that graphical outputs are only
|
||||
supported by lstopo, to reduce dependencies on external libraries.
|
||||
hwloc-ls is identical to lstopo-no-graphics.
|
||||
.
|
||||
.PP
|
||||
The filename specified directly implies the output format that will be
|
||||
used; see the OUTPUT FORMATS section, below. Output formats that
|
||||
support color will indicate specific characteristics about individual
|
||||
CPUs by their color; see the COLORS section, below.

.SH OUTPUT FORMATS
|
||||
.
|
||||
.PP
|
||||
By default, if no output filename is specific, the output is sent
|
||||
to a graphical window if possible in the current environment
|
||||
(DISPLAY environment variable set on Unix, etc.).
|
||||
Otherwise, a text summary is displayed in the console.
|
||||
The console is also used when the program runs from a terminal
|
||||
and the output is redirected to a pipe or file.
|
||||
These default behaviors may be changed by passing \fB\-\-of console\fR
|
||||
to force console mode or \fB\-\-of window\fR for graphical window.
|
||||
.
|
||||
.PP
|
||||
The filename on the command line usually determines the format of the output.
|
||||
There are a few filenames that indicate specific output formats and
|
||||
devices (e.g., a filename of "-" will output a text summary to
|
||||
stdout), but most filenames indicate the desired output format by
|
||||
their suffix (e.g., "topo.png" will output a PNG-format file).
|
||||
.PP
|
||||
The format of the output may also be changed with "\-\-of".
|
||||
For instance, "\-\-of pdf" will generate a PDF-format file on the standard
|
||||
output, while "\-\-of fig toto" will output a Xfig-format file named "toto".
|
||||
.
|
||||
.PP
|
||||
The list of currently supported formats is given below. Any of them may
|
||||
be used with "\-\-of" or as a filename suffix.
|
||||
.TP
|
||||
.B default
|
||||
Send the output to a window or to the console depending on the environment.
|
||||
.
|

.B window
|
||||
Send the output to a graphical window.
|
||||
.
|
||||
.TP
|
||||
.B console
|
||||
Send a text summary to stdout.
|

Binding or unallowed processors are only annotated in this mode
|
||||
if verbose; see the COLORS section, below.
|
||||
.
|
||||
.TP
|
||||
.B ascii
|
||||
Output an ASCII art representation of the map
|
||||
(formerly called \fBtxt\fR).
|

If outputting to stdout and if colors are supported on the terminal,
|
||||
the output will be colorized.

|
||||
.TP
|
||||
\fBtikz\fR or \fBtex\fR

.B svg
|
||||
Output a SVG representation of the map,
|

using Cairo (by default, if supported)
|
||||
or a native SVG backend (fallback, always supported).
|
||||
See \fBcairosvg\fR and \fBnativesvg\fR below.
|

.
|
||||
.TP
|
||||
\fBnativesvg\fR or \fBsvg(native)\fR
|
||||
Output a SVG representation of the map using the native SVG backend.
|
||||
It may be less pretty than the Cairo output, but it is always supported,
|
||||
and SVG objects have attributes for identifying and manipulating them.
|
||||

If the topology is symmetric
|

.B xml
|
||||
If lstopo was compiled with the proper
|
||||
support, lstopo outputs an XML representation of the map.
|
||||
It may be reused later, even on another machine, with lstopo \-\-input,
|
||||
the HWLOC_XMLFILE environment variable, or the hwloc_topology_set_xml()
|
||||
function.
|

.PP
|
||||
The following special names may be used:
|
||||
.TP
|
||||
.B \-
|
||||
Send a text summary to stdout.
|
||||
.
|
||||
.TP
|
||||
.B /dev/stdout
|
||||
Send a text summary to stdout. It is effectively the same as
|
||||
specifying "\-".
|
||||
.
|
||||
.TP
|
||||
.B \-.<format>
|
||||
If the entire filename is "\-.<format>", lstopo behaves as if
|
||||
"\-\-of <format> -" was given, which means a file of the given format
|
||||
is sent to the standard output.

|

.
|
||||
.SH GRAPHICAL OUTPUT
|
||||
The graphical output is made of nested boxes representing
|
||||
the inclusion of objects in the hierarchy of resources.
|
||||
Usually a Machine box contains one or several Package boxes,
|
||||
that contain multiple Core boxes, with one or several PUs each.
|
||||
|
||||
.SS Caches
|
||||
Caches are displayed in a slightly different manner because
|
||||
they do not actually include computing resources such as cores.
|
||||
For instance, a L2 Cache shared by a pair of Cores is drawn
|
||||
as a Cache box on top of two Core boxes
|
||||
(instead of having Core boxes inside the Cache box).
|
||||
|
||||
.SS NUMA nodes and Memory-side Caches
|
||||
By default, NUMA nodes boxes are drawn on top of their local
|
||||
computing resources.
|
||||
For instance, a processor Package containing one NUMA node
|
||||
and four Cores is displayed as a Package box containing
|
||||
the NUMA node box above four Core boxes.
|
||||
If a NUMA node is local to the L3 Cache, the NUMA node is displayed
|
||||
above that Cache box.
|
||||
All this specific drawing strategy for memory objects may be disabled
|
||||
by passing command-line option \fB\-\-children\-order plain\fR.
|
||||
|
||||
If multiple NUMA nodes are attached to the same parent object,
|
||||
they are displayed inside an additional unnamed memory box.
|
||||
|
||||
If some Memory-side Caches exist in front of some NUMA nodes,
|
||||
they are drawn as boxes immediately above them.
|
||||
|
||||
.SS PCI bridges, PCI devices and OS devices
|
||||
The PCI hierarchy is not drawn as a set of included boxes but rather
|
||||
as a tree of bridges (that may actually be switches) with links between them.
|
||||
The tree starts with a small square on the left for the
|
||||
hostbridge or root complex.
|
||||
It ends with PCI device boxes on the right.
|
||||
Intermediate PCI bridges/switches may appear as additional small
|
||||
squares in the middle.
|
||||
|
||||
PCI devices on the right of the tree are boxes containing
|
||||
their PCI bus ID (such as 00:02.3).
|
||||
They may also contain sub-boxes for OS device objects
|
||||
such as a network interface \fIeth0\fR or a CUDA GPU \fIcuda0\fR.
|
||||
|
||||
When there is a single link (horizontal line) on the right of a
|
||||
PCI bridge, it means that a single device or bridge is connected
|
||||
on the secondary PCI bus behind that bridge.
|
||||
When there is a vertical line, it means that multiple devices
|
||||
and/or bridges are connected to the same secondary PCI bus.
|
||||
|
||||
The datarate of a PCI link may be written (in GB/s) right below
|
||||
its drawn line (if the operating system and/or libraries are able
|
||||
to report that information).
|
||||
This datarate is the currently configured speed of the entire PCI link
|
||||
(sum of the bandwidth of all PCI lanes in that link).
|
||||
It may change during execution since some devices are able to
|
||||
slow their PCI links down when idle.

|

.\" Layout Section
|

.\" **************************
|
||||
.SH LAYOUT
|
||||
In its graphical output, lstopo uses simple rectangular heuristics
|
||||
to try to achieve a 4/3 ratio between width and height.
|
||||
Although the hierarchy of resources is properly reflected,
|
||||
the exact physical organization (NUMA distances, rings,
|
||||
complete graphs, etc.) is currently ignored.
|
||||
|
||||
The layout of a level may be changed with \fB\-\-vert\fR, \fB\-\-horiz\fR,
|
||||
and \fB\-\-rect\fR to force a parent object to arrange its children
|
||||
in vertical, horizontal or rectangular manners respectively.
|
||||
|
||||
The position of Memory, I/O and Misc children with respect to other
|
||||
children objects may be changed using \fB\-\-children\-order\fR.
|
||||
This effectivement divides children into multiple sections.
|
||||
The layout of children is first computed inside each section,
|
||||
before sections are placed inside (or below) the parent box.
|
||||
|
||||
The vertical/horizontal/rectangular layout of these additional
|
||||
sections may also be configured through \fB\-\-children\-order\fR.
|
||||

.\" Colors Section

|
||||
.SH COLORS
|
||||
Individual CPUs and NUMA nodes are colored in the graphical output
|
||||
formats to indicate different characteristics:
|
||||
.TP
|
||||
Green
|
||||
The topology is reported as seen by a specific process (see \fB\-\-pid\fR),
|
||||
and the given CPU or NUMA node is in this process CPU or Memory binding mask.
|
||||
.TP
|
||||
White
|
||||
The CPU or NUMA node is in the allowed set (see below).
|
||||
If the topology is reported as seen by a specific process (see \fB\-\-pid\fR),
|
||||
the object is also not in this process binding mask.
|
||||
.TP
|
||||
Red
|
||||
The CPU or NUMA node is not in the allowed set (see below).
|
||||
.
|
||||
.PP
|
||||
The "allowed set" is the set of CPUs or NUMA nodes to which the current process is
|
||||
allowed to bind. The allowed set is usually either inherited from the
|
||||
parent process or set by administrative qpolicies on the system. Linux
|
||||
cpusets are one example of limiting the allowed set for a process and
|
||||
its children to be less than the full set of CPUs or NUMA nodes on the system.
|
||||
.PP
|
||||
Different processes may therefore have different CPUs or NUMA nodes in the allowed
|
||||
set. Hence, invoking lstopo in different contexts and/or as different
|
||||
users may display different colors for the same individual CPUs (e.g.,
|
||||
running lstopo in one context may show a specific CPU as red, but
|
||||
running lstopo in a different context may show the same CPU as white).
|
||||
.PP
|
||||
Some lstopo output modes, e.g. the console mode (default non-graphical output),
|
||||
do not support colors at all.
|
||||
The console mode displays the above characteristics by appending text
|
||||
to each PU line if verbose messages are enabled.
|
||||
.
|
||||
.SH CUSTOM COLORS
|
||||
The colors of different kinds of boxes may be configured with \fB\-\-palette\fR.
|
||||
|
||||
The color of each object in the graphical output may also be enforced by
|
||||
specifying a "lstopoStyle" info attribute in that object.
|
||||
Its value should be a semi-colon separated list of "<attribute>=#rrggbb"
|
||||
where rr, gg and bb are the RGB components of a color,
|
||||
each between 0 and 255, in hexadecimal (00 to ff).
|
||||
.
|
||||
<attribute> may be
|
||||
.TP
|
||||
\fBBackground\fR
|
||||
Sets the background color of the main object box.
|
||||
.TP
|
||||
\fBText\fR
|
||||
Sets the color of the text showing the object name, type, index, etc.
|
||||
.TP
|
||||
\fBText2\fB
|
||||
Sets the color of the additional text near the object,
|
||||
for instance the link speed behind a PCI bridge.
|
||||
.PP
|
||||
The "lstopoStyle" info may be added to a temporarily-saved XML topologies
|
||||
with hwloc-annotate, or with hwloc_obj_add_info().
|
||||
.
|
||||
For instance, to display all core objects in blue (with white names):
|
||||
|
||||
lstopo save.xml
|
||||
hwloc-annotate save.xml save.xml core:all info lstopoStyle "Background=#0000ff;Text=#ffffff"
|
||||
lstopo -i save.xml

.
|
||||
To display the machine topology in textual mode:
|
||||
|
||||
lstopo-no-graphics
|
||||
|
||||
To display the machine topology in ascii-art mode:
|
||||
|
||||
lstopo-no-graphics -.ascii
|
||||
|
||||
To display in graphical mode (assuming that the DISPLAY environment
|
||||
variable is set to a relevant value):
|
||||
|
||||
lstopo
|
||||
|
||||
To export the topology to a PNG file:
|
||||
|
||||
lstopo file.png
|
||||
|
||||
To export an XML file on a machine and later display the corresponding
|
||||
graphical output on another machine:
|
||||
|
||||
machine1$ lstopo file.xml
|
||||
<transfer file.xml from machine1 to machine2>
|
||||
machine2$ lstopo --input file.xml
|
||||
|
||||
To save the current machine topology to XML and later reload it faster
|
||||
while still considering it as the current machine:
|
||||
|
||||
$ lstopo file.xml
|
||||
<...>
|
||||
$ lstopo --input file.xml --thissystem
|
||||
|
||||
To restrict an XML topology to only physical processors 0, 1, 4 and 5:
|
||||
|
||||
lstopo --input file.xml --restrict 0x33 newfile.xml
|
||||
|
||||
To restrict an XML topology to only numa node whose logical index is 1:
|
||||
|
||||
lstopo --input file.xml --restrict $(hwloc-calc --input file.xml node:1) newfile.xml
|
||||
|
||||
To display a summary of the topology:
|
||||
|
||||
lstopo -s
|
||||
|
||||
To get more details about the topology:
|
||||
|
||||
lstopo -v
|
||||
|
||||
To only show cores:
|
||||
|
||||
lstopo --only core
|
||||
|
||||
To show cpusets:
|
||||
|
||||
lstopo --cpuset
|
||||
|
||||
To only show the cpusets of package:
|
||||
|
||||
lstopo --only package --cpuset-only
|
||||
|
||||
Simulate a fake hierarchy; this example shows with 2 NUMA nodes of 2
|
||||
processor units:
|
||||
|
||||
lstopo --input "node:2 2"
|
||||
|
||||
To count the number of logical processors in the system
|
||||
|
||||
lstopo --only pu | wc -l
|
||||
|
||||
To append the kernel release and version to the graphical legend:
|
||||
|
||||
lstopo --append-legend "Kernel release: $(uname -r)" --append-legend "Kernel version: $(uname -v)"
