All MPI routines in Fortran (except for MPI_WTIME and MPI_WTICK )
have an additional argument ierr at the end of the argument list.
ierr is an integer and has the same meaning as the return value of the
routine in C. In Fortran, MPI routines are subroutines, and are invoked with
the call statement.
All MPI objects (e.g., MPI_Datatype , MPI_Comm ) are
of type INTEGER in Fortran.
