I have an MPI/OpenMP application. I would like to launch e.g. 23 MPI processes on 2 nodes (12 cores per node) where one process (e.g. rank 14) should have 2 OMP threads while all the others have a single thread. I want the rank 14 process pinned to 2 cores and the other ranks pinned to a single core. The job is run under Torque/PBS. How can I do that?
