Subject: [OMPI users] Tight integration and interactive sessions with SGE
From: Scott Beardsley (scott_at_[hidden])

I've been using OMPI 1.2.6 tightly integrated with Grid Engine for a bit
now and it works great. However, I'm running into a problem running jobs
from an interactive session (qlogin). I tried just doing "mpirun -np N
/path/to/binary" where N > # of cpus per node but OMPI will just
oversubscribe the node.

Also, I have an initialization script from the vendor that requires
setting up local temporary directories. Prior to migration to OMPI we
just parsed the machines file then went out to each node and created any
necessary temp directories. Is there no way to get a list of machines
with tight integration?
