This enables determining the message sizes for MPI functions. Note: some values like
MPI_COMM_WORLDare pointers in OpenMPI and integers in MPICH. When built with partial MPI support, which uses OpenMPI headers, and used on MPICH applications, values likeMPI_COMM_WORLDwill be displayed as addresses instead of integers.
