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.
