[ale] I need funding and an excuse

[Jim Kinney]

interlinking 512 cpu's through the hyperlink bus is a pretty
impressive feat. Then keeping those nodes in lock-step is a feat. Now
toss in the backchannel memory linking for a NUMA mesh memory model,
it gets pretty impressive.

Granted, they are no longer having to build everything into a tank
full of $3000/gal cooling oil...

It is my understanding that the Cray XT5 scalability involves a
completely parallel scaling process, each cabinet adds exactly the
same cpu/ram/throughput as the next. Most scaling systems are not
linear but asymptotic. That is quite impressive.
