Re: [OMPI users] Using mpiexec to run multiple non-mpi processes

I think you actually have a few options: 1. If I'm reading the original mail right, I don't think you need mpirun/mpiexec at all. When you submit a scripted job to PBS, the script runs on the "mother superior" node -- the first node that was allocated to you. In this, case it's your only

Hi John I'm afraid that the straightforward approach you're trying isn't going to work with Open MPI in its current implementation. I had plans for supporting this kind of operation, butnot happening. And as you discovered, you cannot run mpiexec/mpirun in the background, and the "do-not-wait"
