--------------------------------------------------------------------------
The ompi_info command can be used to provide detailed information on
your Open MPI installation. Syntax:
-a|--all Show all configuration options and MCA parameters
--arch Show architecture Open MPI was compiled on
-c|--config Show configuration options
--color <arg0> Control color coding: auto (default), never,
always
-gmca|--gmca <arg0> <arg1>
Pass global MCA parameters that are applicable to
all contexts (arg0 is the parameter name; arg1 is
the parameter value)
-h|--help Show this help 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)
-l|--level <arg0> Show only variables with at most this level (1-9)
-mca|--mca <arg0> <arg1>
Pass context-specific MCA parameters; they are
considered global if --gmca is not used and only
one context is specified (arg0 is the parameter
name; arg1 is the parameter value)
--param <arg0> <arg1>
Show MCA parameters. The first parameter is the
framework (or the keyword "all"); the second
parameter is the specific component name (or the
keyword "all").
--params <arg0> <arg1>
Synonym for --param
--parsable When used in conjunction with other parameters, the
output is displayed in a machine-parsable format
--parseable Synonym for --parsable
--path <arg0> Show paths that Open MPI was configured with.
Accepts the following parameters: prefix, bindir,
libdir, incdir, mandir, pkglibdir, sysconfdir, all
--pretty-print When used in conjunction with other parameters, the
output is displayed in 'pretty-print' format
(default)
-s|--selected-only Show only variables from selected components
--show-failed Show the components that failed to load along with
the reason why they failed.
-t|--type <arg0> Show internal MCA parameters with the type
specified in parameter.
-V|--version Show version of Open MPI
