-h | --help [<option>]¶

Print the list of options, or the full help for the named option.

-v | --verbose¶

Enable debug output.

-V | --version¶

Print the version of the prte_info tool itself and exit. See --show-version for the versions of PRRTE and its components.

MCA parameters

--prtemca <key> <value>¶

Pass a PRRTE MCA parameter.

Syntax: --prtemca <key> <value>, where key is the parameter name and value is the parameter value.

--pmixmca <key> <value>¶

Pass a PMIx MCA parameter

Syntax: --pmixmca <key> <value>, where key is the parameter name and value is the parameter value.

What to show

-a | --all¶

Show all configuration options and MCA parameters.

--arch¶

Show architecture on which PRRTE was compiled.

-c | --config¶

Show configuration options used to configure PRRTE.

--hostname¶

Show the hostname upon which PRRTE was configured and built.

--param <framework>[:<component>[,<component>...]]¶

Show the MCA parameters of a framework. Given only a framework name (e.g., --param rmaps), every parameter of the framework and of all its components is shown; a comma-delimited list of component names after a colon (e.g., --param rmaps:ppr,round_robin) restricts the output to those components. The keyword all, given either as --param all or as the component list, selects everything.

The framework and its components are one argument: --param rmaps ppr is refused, because ppr is taken as a stray argument. The option may be repeated to show several frameworks.

--params <framework>[:<component>[,<component>...]]¶

Synonym for --param.

--internal¶

Show internal MCA parameters (i.e., parameters not meant to be modified by users).

-t | --type <type>¶

Show MCA parameters of the type specified in the parameter. Accepts the following parameters: unsigned_int, unsigned_long, unsigned_long_long, size_t, string, version_string, bool, and double.

--path <type>¶

Show the paths with which PRRTE was configured. Accepts all or any of: prefix, exec_prefix, bindir, sbindir, libdir, incdir, mandir, pkglibdir, libexecdir, datarootdir, datadir, sysconfdir, sharedstatedir, localstatedir, infodir, pkgdatadir, pkgincludedir. The option may be repeated to show several paths.

--show-version [<what> [<part>]]¶

Show the version of PRRTE or of some of its components. <what> is one of:

The optional <part> selects which part of the version to show: full (the default), major, minor, release, greek, or repo. Given with no argument, the option shows PRRTE’s version and every component’s.

Note that this is distinct from -V/--version, which only prints the version of the prte_info tool itself.

--include-pmix¶

Include PMIx params and build info in output.

--show-failed¶

Show the components that failed to load, along with the reason why they failed.

--selected-only¶

Show only variables from selected (active) components.

Output format

--pretty-print¶

When used in conjunction with other parameters, the output is displayed in “pretty-print” format (default).

--parsable | --parseable¶

When used in conjunction with other parameters, the output is displayed in a machine-parsable format.

--color <hue>¶

Control color coding of the output: auto (the default — color only when stdout is a terminal), never, or always.
