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
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
