Joe,
You are correct this is a ROCKS cluster. I didn't use the the --sge option when
building (I tend to stay more generic, but I should have done that).
Not sure of the OFED release but I don't admin this cluster and the owners are
picky about upgrades (tends to break Lustre).
BTW - the problem was solved. There was a configuration error for the specific
queue. It was found and fixed and things seem to be running normally.
Thanks for help and I'm sorry for disturbing everyone. I wasn't familiar enough
with the error messages to tell if it was OpenMPI or SGE.
TIA!
Jeff

When you built Open-MPI, did you use the
--with-sge
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
