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.
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.
