Notes for Fortran
|
|
Packit Service |
c5cf8c |
All MPI routines in Fortran (except for <tt>MPI_WTIME</tt> and <tt>MPI_WTICK</tt>) have
|
|
Packit Service |
c5cf8c |
an additional argument <tt>ierr</tt> at the end of the argument list. <tt>ierr
|
|
Packit Service |
c5cf8c |
</tt>is an integer and has the same meaning as the return value of the routine
|
|
Packit Service |
c5cf8c |
in C. In Fortran, MPI routines are subroutines, and are invoked with the
|
|
Packit Service |
c5cf8c |
<tt>call</tt> statement.
|
|
Packit Service |
c5cf8c |
|
|
Packit Service |
c5cf8c |
All MPI objects (e.g., <tt>MPI_Datatype</tt>, <tt>MPI_Comm</tt>) are of type <tt>INTEGER
|
|
Packit Service |
c5cf8c |
</tt>in Fortran.
