I'll second that. I've used ocaml to great effect on my tiny little
beowulf (6 nodes) via the MPI bindings. Not only was I able to easily
MPI-ify my code, I was able to write a clean little functor that could
be used to parallelize any bag-of-jobs style parallel task in just a few
lines of code.
So, props to ocaml and Xavier.
