I joined a while back but this "supercomputer" goal seems very interesting,...

Throughout the course of this week, i will be setting up a couple of
machines at home ....(Q9550 & Q6700, nothing fancy) and while is
very unfortunate that WCG is CPU based only and not GPU, i will try
as possible to load each system with at least 8Gb of ram (not sure if that will help) ... but since is only for one week, i don't mind so much for electricity consumption or even bandwidth ...

Glad to be part of such a great project & community.
