oshmem_info - Display information about the Open MPI installation
oshmem_info provides detailed information about the Open MPI/SHMEM installation. It can be useful for at least three common scenarios: 1. Checking local configuration and seeing how Open MPI/SHMEM was installed. 2. Submitting bug reports / help requests to the Open MPI/SHMEM community (see http://www.open-mpi.org/community/help/) 3. Seeing a list of installed Open MPI/SHMEM plugins and querying what MCA parameters they support.
oshmem_info accepts the following options: -a|--all Show all configuration options and MCA parameters --arch Show architecture Open MPI/SHMEM 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/SHMEM was configured and built on --internal Show internal MCA parameters (not meant to be modified by users) --level Show only variables with at most this level (1-9). The default is 1 unless --all is specified without --level in which case the default is 9. See the LEVEL section for more information. -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/SHMEM 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) --selected-only Show only variables from selected components. -V|--version Show version of Open MPI/SHMEM.

oshmem_info Show the default output of options and listing of installed components in a human- readable / prettyprint format. oshmem_info --parsable Show the default output of options and listing of installed components in a machine- parsable format. oshmem_info --param btl openib Show the MCA parameters of the "openib" BTL component in a human-readable / prettyprint format. oshmem_info --param btl openib --parsable Show the MCA parameters of the "openib" BTL component in a machine-parsable format. oshmem_info --path bindir Show the "bindir" that Open MPI was configured with. oshmem_info --version ompi full --parsable Show the full version numbers of Open MPI/SHMEM (including the ORTE and OPAL version numbers) in a machine-readable format. oshmem_info --version btl major Show the major version number of all BTL components in a prettyprint format. oshmem_info --version btl:tcp minor Show the minor version number of the TCP BTL component in a prettyprint format. oshmem_info --all Show all information about the Open MPI/SHMEM installation, including all components that can be found, the MCA parameters that they support, versions of Open MPI/SHMEM and the components, etc.
