It might be possible to use another MPI implementation (Open MPI or
MPICH) and get the process count you're looking for. Of course, I
think you're going to find that your performance is useless -- An MPI
implementation needs to keep a bunch of data around and you don't
have much memory. On the other hand, it might do what you need (swap
can do an awful lot if needed). I can't answer for you if MPI is the
right thing or not. In general, MPI isn't good at decentralized,
dynamic environments. But if it's doing what you need, then why redo
the work you've already put into your prototype?
