prte_info — Display information about the PRRTE installation

16.1.2.1. SYNOPSIS

prte_info [options]

16.1.2.2. DESCRIPTION

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

  1. Checking local configuration and seeing how PRRTE was installed.

  2. Submitting bug reports / help requests to the PRRTE community (see Getting help).

  3. Seeing a list of installed PRRTE plugins and querying what MCA parameters they support.

16.1.2.3. OPTIONS

prte_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 PRRTE was compiled.

  • -c | --config: Show configuration options

  • --hostname: Show the hostname on which PRRTE 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 PRRTE was configured with. Accepts the following parameters: all, 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

  • --color <hue>: Control color coding: auto (default), never, always

  • --show-failed: Show the components that failed to load along with the reason why they failed

  • --selected-only: Show only variables from selected components.
