ompi_info - Display information about the Open MPI installation
ompi_info [options]
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 https://www.open-mpi.org/community/help/)
3. Seeing a list
of installed Open MPI plugins and querying what MCA parameters they support.
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.
- 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
