- split/duplicate functionality - rework inter-node/intra-node handling to allow selection of splitting based on 'shared' or hostname (default). - always creates node communicators at startup: * commInterNode() - between nodes * commLocalNode() - within a node - world-comm is now always a duplicate of MPI_COMM_WORLD to provide better separation from other processes. NB: the inter-node comm is a slight exception to other communicators in that we always retain its list of (global) ranks, even if the local process is not in that communicator. This can help when constructing topology-aware patterns. FIX: non-participating ranks still had knowledge of their potential siblings - after create by group, the procIDs_ of non-participating ranks should be empty (except for the inter-node exception) |
