This would be great if the newest version of ADF would work with MPI on
linux. I found that ADF2000 ran better in parallel with MPICH than with PVM
on Alpha linux. I.e. with two CPUs (on the same node) I would see a scaling
of 1.7 with PVM while a 1.95! scaling with MPI.

I thought the problem with MPICH is that it doesn't support Fortran90 at the
moment. I could be completely off base on this. Comments?
