in reply to OpenMP from Perl?
I know, I'm digging up an old post here, but for future reference the answer is, "Perl has supported MPI for many, many years." Search CPAN for Parallel::MPI and Parallel::MPI::Simple (I prefer the latter: much more perlish). In addition, the already mentioned PDL::Parallel::MPI is properly coded but has has a bad Makefile.PL. Fortunately, hand-tweaking the Makefile.PL to get it to work isn't hard at all if you know how to compile a C-based MPI program on your cluster.
Now, I just wish I could get a hold of Darin so I could fix his Makefile.PL and get it passing tests again...
