Not real sure about why the spacing is like that...
Another concern is about how mpirun is passing the arguments to the
program...  If THAT needs to be patched in the source that'll be a bitch.

Another concern is about how long it takes to start...
a whole second for 5 threads?
1 thread takes about .050...   Is this normal for MPI?  I guess I
should probably check timings for other languages.


Ok, now I'm looking for people who have any experience with MPI.
how many of the files will need to be ported?

None of the examples that I see use anything more than mpi.h.
Are any of the other header files necessary?
