NAMEompi_info - Display information about the Open MPI installation
DESCRIPTIONompi_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 //www.open-mpi.org/community/help/) 3. Seeing a list of installed Open MPI plugins and querying what MCA parameters they support.
OPTIONSompi_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.
EXAMPLESompi_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.
