With regard to condor, I know Duncan Brown at Syracuse has a working script 'condor_mpirun' that's GPL'd.  I'm including a copy of a message that circulated to a LIGO software email list that describes how to run condor mpi jobs.

So you'd submit to a cluster with

     condor_submit  <name-of-script-text-file-included-below>

which would in turn call this script

See http://www.cs.wisc.edu/condor/manual/v7.4/2_9Parallel_Applications.html

for a description of the underlying issues.  I personally haven't used condor in parallel in a few years, but it was particularly convenient when I did.  And it's the submission system I'll likely be using in the future.
