Above 128 processors you need a special
"Cray" router. Above either
512 or 1024 you'll probably need custom SGI setup, possibly a
custom IRIX. At any rate, 32 or 64 processors are pretty fast
(remember as you scale it's harder and harder to get parallel code
to run across all processors), and don't forget to factor in
electricity and cooling. Most hobbyists only run one or two racks.
Do these humongous configurations run a single OS image? If so,
cool!
