Subject: Re: [OMPI users] Missing F90 modules
From: Jeff Squyres (jsquyres_at_[hidden])

This is correct; Open MPI only generates MPI.mod so that you can "use
mpi" in your Fortran app.

I'm not sure that MPI1.mod and MPI2.mod and f90base are -- perhaps
those are somehow specific artifacts of the other MPI implementation,
and/or artifacts of the Fortran compiler...?
