Despite the many press releases to the contrary, Los Alamos (WOO!) continues to hold the top spot with their Roadrunner system (meet-meet!) over Oak Ridge's Jaguar, (note: egg->cpu, not a good pointer). We're on there with our Franklin system at #7: we did a lil upgrade. ;)
The Chinese are present in the top 10, too, btw! Running ... Windows. ew.
There's a small analysis here so you can get a look at the trends.
Oh, yeah, it's Supercomputing 08 in Austin. I'm not there, but there's a lot of news that comes out from this conference. Expect more this week from me.
