The Open MPI that ships with Leopard does not include Fortran support
because OS X does not ship with a Fortran compiler (this was Apple's
decision, not ours). If you have Fortran MPI applications, you'll
need to a) download and install your own Fortran compiler (e.g., http://hpc.sf.net/)
, and b) install your own copy Open MPI that includes Fortran support
(e.g., install it to /opt/openmpi or somesuch -- I do not recommend
installing it over the system-installed Open MPI).
Once you do this, mpif90 should work as expected, and statements like
"use mpi" or "include "mpifh."" should function properly.

Hello again,
I have to be more specific with my problem.
1) I am using the Mac OS X (Leopard) operating system.
When I do uname -a, I get Darwin Kernel Version 9.5.0
2) My code if fortran 90
3) I tried using the mpif90 wrapper and I got the following message
xxxxxxxxxxxxx
mpif90 -c -O3 /Users/lamptey/projectb/src/blag_real_burnmpi.f90
--------------------------------------------------------------------------
Unfortunately, this installation of Open MPI was not compiled with
Fortran 90 support. As such, the mpif90 compiler is non-functional.
--------------------------------------------------------------------------
make: *** [blag_real_burnmpi.o] Error 1
xxxxxxxxxxxxx
4) I have the g95 compiler installed. So when I try using the
g95, (with include "mpif.h" or 'mpif.h'), I get the following mesage:
xxxxxxxxxxxxxx
g95 -fno-pic -c -O3 /Users/lamptey/projectb/src/
blag_real_burnmpi.f90
Error: Can't open included file 'mpif.h'
make: *** [blag_real_burnmpi.o] Error 1
xxxxxxxxxxxxxxx
5) What are people's experience in this case?
Thanks
Ben

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.
Thanks
Ben
