hwloc-annotate - Modify attributes in a XML topology
hwloc-annotate [options] <input.xml> <output.xml> -- <location1> <location2> ... -- <mode> <annotation> hwloc-annotate [options] <input.xml> <output.xml> <location> <mode> <annotation> Note that hwloc(7) provides a detailed explanation of the hwloc system and of valid <location> formats; it should be read before reading this man page.
--ri Remove all info attributes that exist with the same name before adding the new one. This option is only accepted in "info" mode. If the info value is omitted, existing infos are replaced with nothing. --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. --cu Clear the existing userdata from the target objects. If nothing else has to be performed after clearing, mode should be set to none. --cd Clear the existing distances from the topology. If nothing else has to be performed after clearing, mode should be set to none. -h --help Display help message and exit.
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. misc <name> Specifies a new Misc object name. distances <filename> [<flags>] Specifies new distances to be added to the topology using specifications in <filename>. The optional flags (0 unless specified) corresponds to the flags given to the function hwloc_distances_set(). location is ignored in this mode. The first line of the pointed file must be a integer representing a distances kind as defined in hwloc/distances.h. 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 x*y or x*y*z. 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 (see also EXAMPLES below). Multiple locations may be affected if they are specified between --. 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. 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.
hwloc-annotate's operation is best described through several examples. 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
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.
