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.
