NAME

       hwloc-annotate - Modify attributes in a XML topology

SYNOPSIS

       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.

OPTIONS

       --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.

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.

       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.

EXAMPLES

       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

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.
