We _never_ ran on a 21264.  I really don't know why I would even waste the
time correcting your continual wildly inaccurate nonsense.  However, if you
look _hard_ you will find that we ran on a 21164, and we were _not_ the
fastest alphas there, even.  The Kryotech machines were significantly
faster.

Please get your facts right at least _once_ in a while.

We didn't have the fastest hardware in _either_ of those events...  Not by
a long shot...

Guess from ICC experience that should mean Diep <= 1600.  You are killing
yourself...
