I have a proof of concept conversion of the MPICH headers. However, it is 
not so easy, since libmpich.a can be located anywhere on the system; there 
is no Pascal equivalent of mpicc. I haven't decided yet what I'm going to 
do here.

I have also looked at LAMMPI and OpenMPI, looks like they'll be a piece of 
cake lust like MPICH, the only caveat is that h2pas chokes at their header

I don't plan to put effort in OpenMP support; I don't see the need 
for an external library to be able to do multithreaded programming. Focus 
here should be on 100% Pascal implementations.

Also of interrest to HPC users might be the interface to 
FFTW I committed a while ago. For good HPC support we also would need good 
interfaces to BLAS & LAPACK, and/or Pascal based math solutions.

I think so.
