merge Do not show levels that do not have a hierarchical impact. Those names may be substrings of actualįlag names as long as a single one matches, for instanceĭisallowed,thissystem_allowed. Flags may be given as numeric values or as aĬomma-separated list of flag names that are passed to If a bitmap is given after prefix nodeset=, it is the If a bitmap is given as a hexadecimal string, it is used as Such as Linux Cgroups) and loaded here loaded from XML or synthetic. It may be useful if the topology wasĬreated by another process (with different administrative restrictions If local is given, only objects available to theĬurrent process are allowed (default behavior when loading from the disallowed) and also change the set of allowed ones. Include objects disallowed by administrative limitations (implies Offline PUs and NUMA nodes are still ignored. disallowed Include objects disallowed by administrative limitations (e.g Cgroups on no-icaches This is identical to -filter icache:none. no-useless-caches This is identical to -filter cache:structure. This is the old way to specify -filter :none. Type cannot be ignored (usually Machine or System). Graphical and textual outputs, but any object included in them (for Lstopo also offers PU and NUMA node filtering by hiding them in the Hwloc supports filtering any type except PUs and NUMA nodes. If "important" (only applicable to I/O), only "structure", objects are kept when they bring structure to the "none" or not specified, all objects of the given type are :, -filter Filter objects of type, or of any type if is Only show objects of the given type in the textual output. Should be combined with -cpuset or -cpuset-only, otherwise Program instead of hwloc-specific CPU set string format. taskset Show CPU set strings in the format recognized by the taskset command-line C -cpuset-only Only display the cpuset of each object do not display anything else about c -cpuset Display the cpuset of each object. Replace " P#" with the given prefix for physical/OS Replace " L#" with the given prefix for logical indexes. Byĭefault, both logical and physical/OS indexes are displayed for PUs and p -physical Display OS/physical indexes of all objects, with prefix "P#". NUMA nodes, logical only for cores, dies and packages, and no index for l -logical Display hwloc logical indexes of all objects, with prefix "L#".īy default, both logical and physical/OS indexes are displayed for PUs and f -force If the destination file already exists, overwrite it. All of them areĭisplayed, while the default verbose output only shows them if there are windows-processor-groups On Windows, only show information about processor groups. The most energy efficient ones up to the rather higher performance and CPU kinds are displayed in order, starting from All of them are displayed (while theĭefault textual output selects memory attribute details depending on the memattrs Only display memory attributes. May be applied using hwloc-annotate(1) (and it may save their output to See hwloc_distances_transform() for details. Try applying a transformation to distances structures before displaying distances Only display distance matrices. s -silent Reduce the amount of details to show. The hwloc-info tool may be used to display even Value of 3 (or no_ext,no_attr) reverts to the original Of 2 (or no_attr) reverts to the format of hwloc v1.9. Substrings of actual flag names as long as a single one matches. Passed to hwloc_topology_export_synthetic(). Flags may be givenĪs numeric values or as a comma-separated list of flag names that are Enforce flags when exporting to the synthetic format. Those names may be substrings ofĪctual flag names as long as a single one matches. Numeric values or as a comma-separated list of flag names that are passed Enforce flags when exporting to the XML format. input-format Enforce the input in the given format, among xml, fsroot, The string must end with a number of PUs. Topology will contain two NUMA nodes with 3 processing units in each of input Simulate a fake hierarchy (instead of discovering the topology on the When the archivemount program is available, mayĪlso be a tarball containing such Linux or x86 topology files. On x86, may be a directory containing a cpuid Topology files gathered from another machine topology with On Linux, may be a directory containing the is "-", the standard input may be used as a XML Hwloc, it may be a XML file exported by a previous hwloc program.
