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.
qlogin will create a completely fresh bash, which is not aware of
running under SGE. Although you could set the SGE_* variables by
hand, it's easier to use an interactive session with:
$ qrsh -pe orte 4 /path/to/binary
If you really need a shell, you can get one with:
$ qrsh -pe orte 4 bash -il
-- Reuti
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?
