- UPstream::globalComm constant always refers to MPI_COMM_WORLD but UPstream::worldComm could be MPI_COMM_WORLD (single world) or a dedicated local communicator (for multi-world). - provide a Pstream wrapped version of MPI_COMM_SELF, references as UPstream::selfComm - UPstream::isUserComm(label) test for additional user-defined communicators
