Often, a PBS submission system will provide the host information to MPI automatically.
However, you will have to refer to the documentation for your particular cluster (or talk to the sysadmin, as Justin mentioned) to determine if your particular cluster behaves this way, which MPI process startup program you need to use (mpiexec, mpirun, ibrun, etc.) and any additional flags needed to run parallel jobs on that cluster. -- Josh On Wed, 2011-05-25 at 22:03 -0400, Justin A.
