Re: [Condor-users] Condor-C -> PBS/MPI possibility under v6.8?

[Mark Calleja <M.Calleja@xxxxxxxxxxxxxxx>]

OK, I'll answer my own question. It is possible to run such remote MPI jobs 
under PBS using Condor-C, but the interface is a bit clunky. I had to 
submit a wrapper to the actual executable and nominate the executable via 
Condor to be mpirun (for MPICH; obviously one would use the appropriate 
command for LAM or whatever flavour of MPI).

Thanks to Jaime Frey for a useful discussion on the subject.
