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.
