Hi Mariam, Patrick,

Please consult the documentation for the system you're using or the specific MPI implementation you're using for the appropriate syntax to use, as it will be different for different people, machines, environments, and configurations. But I was not able to run: mpiexec –hosts 2 localhost 1 remotehost 1 > pvserver > > Can you provide some more context? What actually happens? What didn't work? Were there any error messages? etc. Thanks ---------- Chuck Atkins Staff R&D Engineer, Scientific Computing Kitware, Inc.
