NAME

       hwloc-annotate - Add info attributes to a XML topology

SYNOPSIS

       hwloc-annotate [options] <input.xml> <output.xml> <location> <mode> <annotation>

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.

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 info 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 info infoname infovalue

       Change socket objects to green with red text in the lstopo graphical output:

           $     hwloc-annotate     topo.xml     topo.xml     socket: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.
