NAME
hwloc-annotate - Add info attributes to a XML topology SYNOPSIS
hwloc-annotate [options] <input.xml> <output.xml> <location> <mode> <annotation> OPTIONS
--ci Clear the existing info attributes in the target objects before annotating. If no new annotation has to be added after clearing, mode should be set to none. 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. The annotation may be string info attributes. This is specified by the mode: info <name> <value> Specifies a new string info attribute whose name is name and value is value. none No new annotation is added. This is useful when clearing existing attributes. 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 location: all annotates all objects in the topology. root annotates the root object of the topology. <type>:all annotates all objects of the given type. <type>:<index> annotates the object of the given type and index. The index is logical. NOTE: The existing annotations may be listed with hwloc-info. 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-annotate utility. EXAMPLES
hwloc-annotate's operation is best described through several examples. Add an info attribute to all Core objects: $ hwloc-annotate input.xml output.xml Core:all infoname infovalue Add an info attribute to the root object of the topology and modify the input XML directly: $ hwloc-annotate file.xml file.xml root infoname infovalue RETURN VALUE
Upon successful execution, hwloc-annotate generates the output topology. The return value is 0. hwloc-annotate will return nonzero if any kind of error occurs, such as (but not limited to) failure to parse the command line. SEE ALSO

NAME
hwloc-distances - Displays distance matrices SYNOPSIS
hwloc-distances [options] OPTIONS
-l --logical Display hwloc logical indexes (default) instead of physical/OS indexes. -p --physical Display OS/physical indexes instead of hwloc logical indexes. -i <file>, --input <file> Read topology from XML file <file> (instead of discovering the topology on the local machine). If <file> is "-", the standard input is used. XML support must have been compiled in to hwloc for this option to be usable. -i <directory>, --input <directory> Read topology from the chroot specified by <directory> (instead of discovering the topology on the local machine). This option is generally only available on Linux. The chroot was usually created by gathering another machine topology with hwloc-gather-topology. -i <specification>, --input <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. --if <format>, --input-format <format> Enforce the input in the given format, among xml, fsroot and synthetic. --restrict <cpuset> Restrict the topology to the given cpuset. -v Verbose messages. --version Report version and exit. DESCRIPTION
hwloc-distances displays also distance matrices attached to the topology. A breadth-first traversal of the topology is performed starting from the root to find all distance matrices. NOTE: lstopo may also display distance matrices in its verbose textual output. However lstopo only prints matrices that cover the entire topology while hwloc-distances also displays matrices that ignore part of the topology. EXAMPLES
On a quad-socket opteron machine: $ hwloc-distances Latency matrix between 4 NUMANodes (depth 2) by logical indexes: index 0 1 2 3 0 1.000 1.600 2.200 2.200 1 1.600 1.000 2.200 2.200 2 2.200 2.200 1.000 1.600 3 2.200 2.200 1.600 1.000 RETURN VALUE
Upon successful execution, hwloc-distances returns 0. hwloc-distances will return nonzero if any kind of error occurs, such as (but not limited to) failure to parse the command line. SEE ALSO
