Re: [OMPI users] Missing F90 modules

[Brock Palen]

I have seen strange things about fortran compilers and the suffix of files.

use mpi



Try renaming carfoo.f  to cartfoo.f90  and try again.

is a fortran 90 thing, not 77, many compilers want fortran 90 codes to end in .f90 or .F90 I have attached a helloworld.f90 that uses use mpi that works on our openmpi installs.

helloworld.f90

Please excuse my admittedly gross ignorance of all things Fortran but why does "include 'mpif.h'" work but "use mpi" does not? When I try the "use mpi" method I get errors like: No specific match can be found for the generic subprogram call "MPI_CART_GET" From the googling I've done it seems like "use mpi" is preferred [1]. I've made sure that my $LD_LIBRARY_PATH has the directory that MPI.mod is in.
