I have produced a thickish binding for MPI that I intend to release
soon. It is by no means complete. I have implemented the Group and
Communicator management functions and have extended the stream
attributes for communication and broadcast. 

The hardest step is always the most difficult. MPI may be a standard but
the header files "mpi.h" reflect different implementations. The tool 
cbind (Mitch Gart) was used to get a first iteration for a thin binding. 

One milestone was the function MPI_Init(**argc, **argv) that uses
command line parameters. So far the most elegant way to use MPI is
to call a procedure with spec

	AdaProg(C : Communicator) 

from a C-Wrapper.

The binding has been tested on

	Machine		Gnat	MPI
	Sun4(SunOs)	3.09	mpich
	IBM SP2		3.07	vendor
	Meiko CS2	3.07	mpich

Your interest will certainly act as a stimulus for me to do further
work.
