NAME

       oshmem_info - Display information about the Open MPI installation

SYNOPSIS

       oshmem_info [options]

DESCRIPTION

       oshmem_info  provides  detailed information about the Open MPI/SHMEM installation.  It can
       be useful for at least three common scenarios:

       1. Checking local configuration and seeing how Open MPI/SHMEM was installed.

       2.  Submitting  bug  reports  /  help  requests  to  the  Open  MPI/SHMEM  community  (see
       http://www.open-mpi.org/community/help/)

       3. Seeing a list of installed Open MPI/SHMEM plugins and querying what MCA parameters they
       support.

OPTIONS

       oshmem_info accepts the following options:

       -a|--all
               Show all configuration options and MCA parameters

       --arch  Show architecture Open MPI/SHMEM was compiled on

       -c|--config
               Show configuration options

       -gmca|--gmca <param> <value>
               Pass global MCA parameters that are applicable to all contexts.

       -h|--help
               Shows help / usage message

       --hostname
               Show the hostname that Open MPI/SHMEM was configured and built on

       --internal
               Show internal MCA parameters (not meant to be modified by users)

       --level Show only variables with at most this level (1-9). The default is 1  unless  --all
               is specified without --level in which case the default is 9. See the LEVEL section
               for more information.

       -mca|--mca <param> <value>
               Pass context-specific MCA parameters; they are considered global if --gmca is  not
               used and only one context is specified.

       --param <type> <component>
               Show MCA parameters.  The first parameter is the type of the component to display;
               the second parameter is the specific component to display (or the  keyword  "all",
               meaning "display all components of this type").

       --parsable
               When  used  in  conjunction  with  other  parameters, the output is displayed in a
               machine-parsable format --parseable Synonym for --parsable

       --path <type>
               Show paths that  Open  MPI/SHMEM  was  configured  with.   Accepts  the  following
               parameters: prefix, bindir, libdir, incdir, pkglibdir, sysconfdir.

       --pretty
               When  used  in  conjunction  with  other  parameters,  the  output is displayed in
               'prettyprint' format (default)

       --selected-only
               Show only variables from selected components.

       -V|--version
               Show version of Open MPI/SHMEM.

EXAMPLES

       oshmem_info

       oshmem_info --param btl openib
           Show the  MCA  parameters  of  the  "openib"  BTL  component  in  a  human-readable  /
           prettyprint format.

       oshmem_info --param btl openib --parsable
           Show the MCA parameters of the "openib" BTL component in a machine-parsable format.
