Dave,
Thanks for the suggestion, adding "-mca plm ^rshd" did force mpirun to
spawn things via qrsh rather than SSH. My problem is solved!

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.
I can't access the web site, but there's an item in the notes on the
download page about the bug. It must also be in the mail archive in a
thread with me included.
Are
you suggesting that I launch mpirun similar to this?
mpirun -mca plm ^rshd ...?
Yes, or put it in openmpi-mca-params.conf. It's harmless with 1.4.
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.
OK. (I'd expect a separate PE for each node set to enforce that.)
