FWIW, for the Fortran MPI programmers out there, the MPI Forum is hard
at work on a new Fortran 03 set of bindings for MPI-3. We have a
prototype in a side branch of Open MPI that is "mostly" working. We

At a slight tangent, if there are flags that might be helpful to add to
gfortran for compatibility (e.g. logical cons

Hi,
I want to avoid separate MPI distributions since we compile many
MPI software packages. Having more than one MPI distribution
(at least) doubles the amount of work.

I should clarify -- that *probably* works.
The .mod file are essentially precompiled headers. Assuming that all
the data types and sizes are the same between gfortran and ifort, you
should be ok. Many of OMPI'

That's what I do and then use mpi-selector to switch between versions as
