I almost hate to enter the conversation at this point as this seems to be
progressing quite nicely; however, I believe the premise is becoming a bit
skewed and perhaps short sighted. The "envelope pushing" expertise
associated with this group may or may not be specific to environments of
128 to 1,000+ nodes or CPU's. I'd be willing to bet that many of us are
working with groups developing code that can take advantage of ten thousand
or more CPU's.
The premise here should not be limited to what x-vendor can accomplish
today..rather what they can be driven to through the brain-power of groups
like this. As mentioned by Greg, 1000 CPU's is an easily (ok..maybe not so
easy but) obtainable goal. It's not what vendors can do now, but what is
needed to support the needs of science and research. Drive the numbers guys!!
And where is Robert when he's really needed...vacation?
