4 X 850 means 4 2.4ghz opterons.  At the last CCT, I ran on 4 2.2ghz opterons.
Speeds will probably average 9-10M NPS.

Comparing crafty to the commercials is not easy.  I know what my SMP speedup
looks like, because I have run on all sorts of duals and quads.  I don't see
speedup reports from commercial parallel chess programs, although a few users
have reported not-so-good-numbers from time to time, but it is never obvious
whether the speedup problems are hardware, software or set-up induced.

I don't see any need to try to predict the results.  We ought to know soon
enough without wasting brain-power on idle speculation...
