Condor should be able to run OpenMPI jobs with the condor Parallel
Universe which is new in condor 6.7. We provide sample scripts for Lam
and mpich jobs startup. It should be easy to modify the mpich startup
script for OpenMPI, it looks like the only thing you will need to change
is the way to specify that "condor_! ssh" is the "ssh" that mpirun uses to
launch execute nodes. For openmpi, you can modify the mpich example
file so that the mpirun line has something like
mpirun --mca pls_rsh_agent path_to_condor_ssh
and that should do it.
