Subject: Re: [OMPI devel] ompi_info

Jeff is indeed correct, the compromise we reached was to default to the historical behavior of showing only the parameters of selected components and have an option to show everything else.


PS: Shouldn't "ompi_info --param all all" be identical to "ompi_info --all"?

Users have come to rely on this behavior to test that OMPI is honoring their $HOME/.openmpi-mca-params.conf file (for example) because -- at least prior to new ompi_info -- there was no other way to verify that.
