Here is a simple example:
I am trying to compile the folowing fortran program stored in file mpi1.f90
program who_am_i
!----------------------------------
implicit none
include 'mpif.h'
integer :: nb_procs,rang,code
!----------------------------------
call mpi_init(code)
call mpi_comm_size(MPI_COMM_WORLD,nb_procs,code)
call mpi_comm_rank(MPI_COMM_WORLD,rang,code)
print *,'I am process number ',rang,'/',nb_procs
call mpi_finalize(code)
end program who_am_i
this program compiles nicelly with lam-mpi on Mac OS X 10.4 (Tiger) and of
course, it runs.
On Leopard, things are different, compilation fails:
mpif77 mpi1.f90 -o mpi1
gives:
Royal-Gala:Examples chris$ mpif77 mpi1.f90
