GM itself is supported and maintenance releases are tested (no more
development releases), but Open-MPI/GM is not tested at the moment. GM
does not run on Myri-10G NICs, so we have to use a smaller pool of
machines with Myrinet 2000 NICs in them. Human usage and MTT runs for
Open-MPI/MX have priority and MTT for Open-MPI/GM has not run for a
while :-(
We will try to resume MTT testing with Open-MPI/GM when we have the
resources. In the meantime, we'll look into the segfault.
