I have just recently added support for several other MPI's, including
MPICH2 (did you really mean MVAPICH2? I added support for that as
well) in a development branch that we are just about to merge into
the trunk. We'll then be deploying this new version out to the OMPI
core testing group within a week or two.
However, you're free to use this branch now. Get a checkout of:
http://svn.open-mpi.org/svn/mtt/tmp/jms-new-parser
There is a sample/template INI file for the OMPI collective
performance bake-off that we're going to undertake shortly -- it has
template sections for lots of different MPI's. Look at samples/ompi-
core-perf-testing.ini. You'll see some SLURM-specific stuff because
that's what I run on my cluster, but adapting it to use a hostfile /
hostlist would not be difficult (especially if you have a fixed/known
list of hosts in advance).
Note that the template INI file is a slightly different format than
the INI files that are currently being used on the OMPI core nightly
regression testing (meaning: we changed a few of the parsing rules).
So don't start with a nightly regression testing INI file -- you must
start from one of the samples on the jms-new-parser branch (every
samples/*ini file on the jms-new-parser branch should be updated with
the new formatting rules).
Does this help? Let me know if you have further questions.

Actually, you are. :) Membership is by organization, not
individuals, and Mellanox is a core Open MPI member.
