Did anyone else notice that once the Columbia numbers were publically
announced and within a day or two of the Top500 announcement,
BlueGene/L suddenly appeared on the list at the top? I thought there was
some kind of deadline, but evidently, if you are a sponsor of the Top500
site, then deadlines mean little.

However, I guess it's understandable since, as rgb points out, the Top500
is an advertising thing anyway. Doug Eadline has a great quote about
the SuperComputer show and the Top500. I can't repeat the quote here,
but it has something to do with "size." After experiencing the show, the
observation is ABSOLUTELY right on target.

Also, the CPUs in BlueGene/L are specialized. I haven't heard anything
from IBM about marketing those CPUs in a real system. In talking to
IBM they are even reluctant to talk to us about their 970 or Power5
systems, nevermind testing them. At least Cray created a product from
Red Storm.

Enjoy your day!
