NOTES FOR FORTRAN

       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.
