Spike, I wasn't picking on you with the flop/flops comment. The Wired
article had it wrong, too. It's widespread, and I should probably just
get over it.

My pet massively parallel project is protein folding via Folding at home,
which reached the petaflops milestone long before Roadrunner or
Jaguar, but didn't garner big press because it didn't involve millions
of dollars of tax money.

Good question. I think the new i7 chips are going to raise the bar.

According to http://www.macobserver.com/analysis/2008/11/17.1.shtml an
8-core Mac Pro should clock in at ~91 gigaflops.
