pmix_info — Display information about the PMIx installation

pmix_info [options]

pmix_info provides detailed information about the PMIx installation. It can be useful for at least three common scenarios:

1.
Checking local configuration and seeing how PMIx was installed.
2.
Submitting bug reports / help requests to the PMIx community (see Getting help).
3.
Seeing a list of installed PMIx plugins and querying what MCA parameters they support.

pmix_info accepts the following options:

  • -h | --help <arg0>: Show help message. If the optional argument is not provided, then a generalized help message similar to the information provided here is returned. If an argument is provided, then a more detailed help message for that specific command line option is returned.
  • -v | --verbose: Enable debug output.
  • -V | --version: Print version and exit.
  • -a | --all: Show all configuration options and MCA parameters.
  • --arch: Show architecture on which PMIx was compiled.
  • -c | --config: Show configuration options
  • --hostname: Show the hostname on which PMIx was configured and built.
  • --internal: Show internal MCA parameters (not meant to be modified by users).
  • --param <arg0>:<arg1>,<arg2>: Show MCA parameters. The first parameter is the framework (or the keyword “all”); the second parameter is a comma-delimited list of specific component names (if only <arg0> is given, then all components will be reported).
  • --path <type>: Show paths that PMIx was configured with. Accepts the following parameters: prefix, bindir, libdir, incdir, pkglibdir, sysconfdir.
  • --pretty-print: When used in conjunction with other parameters, the output is displayed in “prettyprint” format (default)
  • --parsable: When used in conjunction with other parameters, the output is displayed in a machine-parsable format
  • --parseable: Synonym for --parsable
  • --show-failed: Show the components that failed to load along with the reason why they failed
  • --selected-only: Show only variables from selected components.

Returns 0 if successful, non-zero if an error is encountered
