... communication partners in the form source/dest are given in this order. For example, for the process with rank=5,itiscoords[1]=1, and there- fore source=9 (lower neighbor in dimension 0) and dest=1 (upper ... and source for each pro- cess. These are then used as parameters for MPI Sendrecv(). The following diagram illustrates the exchange. For each process, its rank, its Carte...
