When you built Open-MPI, did you use the
switch? Or if this is an OFED release, is it possible that this wasn't specified?
FWIW, this looks like a Rocks compute node ("compute-2-2.local" gives that away). The OFED Rolls in Rocks have had a few issues in the past with how they were built, so you may be running into that. If you didn't build it yourself,
I'd suggest at least giving that a try.
Alternatively, OFED-1.4 is pretty good. Has a later version of Open-MPI than 1.3.x
