NAME

       ompi_info - Display information about the Open MPI installation

SYNOPSIS

       ompi_info [options]

DESCRIPTION

       ompi_info  provides  detailed  information about the Open MPI installa-
       tion.  It can be useful for at least three common scenarios:

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

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

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

OPTIONS

       ompi_info accepts the following options:

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

       --arch  Show architecture Open MPI 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 was configured and built on

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

       -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 com-
               ponent  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>
       -v|--version <component> <scope>
               Show  version  of  Open MPI or a component.  <component> can be
               the keywords "ompi" or "all", the name of  a  framework  (e.g.,
               "coll" shows all components in the coll framework), or the name
               of a specific component (e.g., "pls:rsh" shows the  information
               from  the  rsh  PLS  component).   <scope> can be one of: full,
               major, minor, release, greek, svn.

           Show  the  major  version  number  of all BTL components in a pret-
           typrint format.

       ompi_info --version btl:tcp minor
           Show the minor version number of the TCP BTL component in  a  pret-
