Thanks to Jay and Robby for their replies. I honestly don't care what form of message-passing I use, I just don't want to
write my own. My app will eventually run different very large programs (100,000 lines of C-like procedural code) on clustered machines controlled by a head node. I have to rewrite all my original code in SOMETHING (it's in PASCAL because that's what I'm virtuosic in and that's what I've been using for 25 years) and I was preparing to rewrite in C and use MPI, but I've decided it's better to switch all at once. If I learn Gambit Scheme (that apparently includes an Erlang link), how far from Racket is that? Or is there a better solution? For instance, should I use Racket (which is my preference because we might start teaching it here) and assume that by the time I need it (a few years from now) there will be some intrinsic clustering facilities?
