OMPI_INFO(1)                       Open MPI                       OMPI_INFO(1)



NAME
       ompi_info - Display information about the Open MPI installation

SYNOPSIS
       ompi_info [options]

DESCRIPTION
       ompi_info provides detailed information about the Open MPI
       installation.  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
               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 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)

       -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.

EXAMPLES
       ompi_info
           Show the default output of options and listing of installed
           components in a human-readable / prettyprint format.

       ompi_info --parsable
           Show the default output of options and listing of installed
           components in a machine-parsable format.

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

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

       ompi_info --path bindir
           Show the "bindir" that Open MPI was configured with.

       ompi_info --version ompi full --parsable
           Show the full version numbers of Open MPI (including the ORTE and
           OPAL version numbers) in a machine-readable format.

       ompi_info --version btl major
           Show the major version number of all BTL components in a
           prettyprint format.

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

       ompi_info --all
           Show all information about the Open MPI installation, including all
           components that can be found, the MCA parameters that they support,
           versions of Open MPI and the components, etc.
