The list has always been a highly debated and contested flexing of one's supercomputing might. This list was no dissapointment. The biggest story of this year was the backyard brawl between ORNL's Cray XT5 system, Jagaur, and the reining champ, RoadRunner at LANL. Fighters, to your corners! It was widely publicized that Jaguar had a distinct chance to inch out the RoadRunner. Alas, Wyle-E-Coyote never wins. The folks at IBM/LANL did a quick upgrade in June in order to ensure their command. It worked. RoadRunner is #1, Jaguar #2. Ladies and gentlefolk, we officially have two 1PF+ machines. The number three system was no slouch either. NASA Ames took #3 with Pleiades, an SGI Altix ICE system spinning at 487Tflops. #4 and #5 are both BlueGene's of various flavors located at LLNL and Argonne respectively. TACC fell to #6 with Ranger, their massive Sun machine. Cray took #7 and #8 with an XT5 at NERSC and an XT4 at ORNL. Sandia/Cray took in #9 with new upgrades to the Red Storm machine. All in all, we've seen some incredible performance jumps this year. You now have to top 400Tflops in order to inch yourself into the top six. Wow. For more info on the latest Top500, read the full release here.

Submission + - The 110 Million Dollar Button

Reservoir Hill writes: "The "I'm Feeling Lucky" button on Google's search page may cost the company up to $110 million in lost ad revenue every year according to a report in American Public Media's Marketplace. Tom Chavez says that since the company makes money selling ads on its search results page, the 1% of users who use the "I'm Feeling Lucky" button never see Google's ads because the button automatically directs them to a non-Google site reducing Google's ad revenue. So why does Google keep the button? Marisa Mayer, Google's vice president responsible for everything on the search page, says that "it's possible just to become too dry, too corporate, too much about making money" and the "I'm Feeling Lucky," button reminds you that "people here have personality." Web usability expert Jacob Nielsen says the whimsy serves another business purpose: "Oh we're just two kind of grad students hanging out and having a beer and having a grand old time," not you know, "We are 16,000 people working on undermining your privacy.""
