what kinds of things do they do?

I've run full-scale cluster environments on my laptop ;)

I think I would not bother to set up anything less than 4-ish nodes.

you probably don't mean pentiums (P5, followon from the P4, _soo_ fin de siecle)

I find that 2GB/core covers most parallel apps.  1G/core is a bit tight,
though there are a substantial number of serial apps (or embarassingly
parallel) at a measly 5-50 MB.
