1) When I use MPI_SHORT instead of short to count the number of data transferred I get an array that is half the size. (ie MPI_Isend(&data2[0][0][0], (int) (sizeof(data2)/sizeof(MPI_SHORT)), MPI_SHORT, rank, 123, cartcomm,&request[rank-1]);
MPI_SHORT and the other data types are actually macros that resolve to MPI_Datatype which is a pointer to a struct.
