Short version: remove opal_paffinity_alone and restore mpi_paffinity_alone. ORTE makes various information available for the MPI layer to decide what it wants to do in terms of processor affinity. Details: * remove opal_paffinity_alone MCA param; restore mpi_paffinity_alone MCA param * move opal_paffinity_slot_list param registration to paffinity base * ompi_mpi_init() calls opal_paffinity_base_slot_list_set(); if that succeeds use that. If no slot list was set, see if mpi_paffinity_alone was set. If so, bind this process to its Node Local Rank (NLR). The NLR is the ORTE-maintained slot ID; if you COMM_SPAWN to a host in this ORTE universe that already has procs on it, the NLR for the new job will start at N (not 0). So this is slightly better than mpi_paffinity_alone in the v1.2 series. * If a slot list is specified *and* mpi_paffinity_alone is set, we display an error and abort. * Remove calls from rmaps/rank_file component to register and lookup opal_paffinity mca params. * Remove code in orte/odls that set affinities - instead, have them just pass a slot_list if it exists. * Cleanup the orte/odls code that determined oversubscribed/want_processor as these were just opposites of each other.
