Hi Dave,
I looked through the INSTALL, VERSION, NEWS, and README files in the
1.5.4 openmpi tarball but didn't see what you were referring to. Are you
suggesting that I launch mpirun similar to this?
mpirun -mca plm ^rshd ...?
What I meant by "the same parallel environment setup" was that the PE in
SGE was defined the same way:
$ qconf -sp orte
pe_name orte
slots 9999
user_lists NONE
xuser_lists NONE
start_proc_args /bin/true
stop_proc_args /bin/true
allocation_rule $round_robin
control_slaves TRUE
job_is_first_task FALSE
urgency_slots min
accounting_summary FALSE
Even though I have RHEL 5 and RHEL 6 nodes in the same cluster they
never run the same MPI job; it's always either all RHEL 5 nodes or all
RHEL 6.

Hello Open MPI community,
I'm running the openmpi 1.5.3 package as provided by Redhat Enterprise
Linux 6, along with SGE 6.2u3. I've discovered that under RHEL 5 orted
gets spawned via qrsh and under RHEL 6 orted gets spanwed via
SSH. This is happening in the same cluster environment with the same
parallel environment setup. I want orted to get spawned via qrsh
because we impose memory limits if a job is spawned through SSH.
[I'd have thought you'd want qrsh to get tight integration regardless.]
I cannot determine WHY the behavior is different from RHEL 5 to RHEL
6. In the former I'm using the openmpi 1.4.3 package, in the latter
I'm using openmpi 1.5.3. Both are supposedly built to support the
gridengine ras.
See the release notes for 1.5.4. The workaround I was given is
plm = ^rshd
Aha, thx for reminding me of it - so it's still broken.

Does "the same parallel environment setup" mean mixing 1.4 and 1.5? I
thought they weren't binary compatible.
