Follow-up to the 2nd question which I now realize is something else. I can see output when I do: ompi_info --param coll fca with a version of OpenMPI that was built with --prefix set to its installed location.
I cannot get the output when I use a relocated version, i.e. built in one place and installed in another, even after I set OPAL_PREFIX to reflect the installed location.

Sometimes I want to use one of the option flags, for example today it is mtl_mxm_verbose. How do I discover the valid possible values of various MCA parameters? I've tried ompi_info --all but it does not show the possible values, only the current value I've tried ompi_info --param <framework> all but no matter what string I give for framework, I get no output at all. Thanks
