[Beowulf] HPC fault tolerance using virtualization

[Egan Ford]

Ha!  :-)

I've put a few GigE systems in the Top100, and if the stars align you'll see
a Top20 GigE system in next weeks list.  That's ONE GigE to each node
oversubscribed 4:1.  Sadly no flashing lights, and since its 100% water
cooled with low velocity fans, there is almost no noise.
