All MPI routines in Fortran (except for ’MPI_WTIME’ and ’MPI_WTICK’) have an additional argument ’ierr’ at the end of the argument list. 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’, ’MPI_File’) are of type ’INTEGER’ in Fortran.
