  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.

## OPTIONS

**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.
