Please keep us posted. Althought, I doubt if the AF and Navy would approve
of a giant Quake game.......unless....Never mind.
Yes, the death or mere glitch of a single node can be a killer. LAM at least
good at telling you whose alive at the start. I confess to a daily check on
the progress of the current run. At low frequencies (70 MHz) it takes those
60 nodes about 26 hours to simulate one wave length.
What about grid computing? Seti at home style. It is certainly immune to single
node failure. With dedicated systems you could keep things in sync easier.

They that can give up essential liberty
to obtain a little temporary safety
deserve neither liberty nor safety.
