Hello,
I am new at using open-mpi and will like to know something basic.
What is the equivalent of the "mpif.h" in open-mpi which is normally
"included" at
the beginning of mpi codes (fortran in this case).
I shall appreciate that for cpp as well.
For Fortran:
INCLUDE "mpif.h"
For C:
#include <mpi.h>
If you use the compiler wrappers (mpif90, mpicc, etc.), they should be
able to find the include files.
MPI source codes are *supposed* to run unchanged as you move them from
one MPI to another, even if the procedures for compiling and launching
those codes vary.
P.S. It's "Open<space>MPI" rather than "open-mpi". :^)
