What are people using for parallel packages these days?

I've been daydreaming for some time about a minature OS that runs in the systray in win32 and as a daemon in linux... You know, that runs perl and has some kind of shared filesystem and/or shared memory.

It occurred to me recently that it might already exist. I looked at Parallel::Pvm a little and it seems to go the right direction perhaps. jcwren talks about parallelism a little here: Parallel Processing, Processes, and Threads. I found one article here that mentioned Parallel::Pvm and some other system that seemed abandoned/forgotten (but it wasn't perl based). I can't find that article now...

I found some offsite things (eg, parawiki and Parallel_computing), but I was looking for perl specific things — all the nodes here that talk about it seem to be several years old — or at least, I don't know how to look for the newer ones.

At one point, I had hoped POE would help — and for all I know, it does; but it seemed woefully single threaded to me.

Again, what are people using for parallel packages these days? I have a sneaking suspicion it hasn't changed all that much since the older posts I've found. That, or everyone just uses threads and/or message passing by hand maybe?

UPDATES and CLARIFICATIONS:

  1. I intentionally didn't say what I meant by parallel because I'm interested in any links people have. Personally, I'm mostly interested multi-computer scenarios, but multi-processor scenarios would be interesting to read about also.
