The ompi_info command can be used to provide detailed information on
your Open MPI installation.  Syntax:

-a|--all                 Show all configuration options and MCA parameters
   --arch                Show architecture Open MPI was compiled on
-c|--config              Show configuration options
   --color <arg0>        Control color coding: auto (default), never,
                         always
   -gmca|--gmca <arg0> <arg1>
                         Pass global MCA parameters that are applicable to
                         all contexts (arg0 is the parameter name; arg1 is
                         the parameter value)
-h|--help                Show this help 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)
-l|--level <arg0>        Show only variables with at most this level (1-9)
   -mca|--mca <arg0> <arg1>
                         Pass context-specific MCA parameters; they are
                         considered global if --gmca is not used and only
                         one context is specified (arg0 is the parameter
                         name; arg1 is the parameter value)
   --param <arg0> <arg1>
                         Show MCA parameters.  The first parameter is the
                         framework (or the keyword "all"); the second
                         parameter is the specific component name (or the
                         keyword "all").
   --params <arg0> <arg1>
                         Synonym for --param
   --parsable            When used in conjunction with other parameters, the
                         output is displayed in a machine-parsable format
   --parseable           Synonym for --parsable
   --path <arg0>         Show paths that Open MPI was configured with.
                         Accepts the following parameters: prefix, bindir,
                         libdir, incdir, mandir, pkglibdir, sysconfdir, all
   --pretty-print        When used in conjunction with other parameters, the
                         output is displayed in 'pretty-print' format
                         (default)
-s|--selected-only       Show only variables from selected components
   --show-failed         Show the components that failed to load along with
                         the reason why they failed.
-t|--type <arg0>         Show internal MCA parameters with the type
                         specified in parameter.
-V|--version             Show version of Open MPI
