At my lab yesterday, all of us got to work and built up a cluster of 16 nodes.
A bit on specs:
8, 32-bit Intel Pentium IV @ 2.8 GHz with 2 GB RAM
8, 64-bit Intel Core Duo @ 2.66 GHz with 1 GB RAM (contributed by Intel India)
Though there is lot to setup still, cheers to all TCGians. Check out some snaps taken from my mobile.
