http://news.yahoo.com/s/ap/20080609...zU0NTFiYmY2YjY0Y2Q0MWRlYjBiYWRlNDYEUl9sdHADMQ-- But the Roadrunner supercomputer, named after the New Mexico state bird, is nothing like a video game. The interconnecting system occupies 6,000 square feet with 57 miles of fiber optics and weighs 500,000 pounds. Although made from commercial parts, the computer consists of 6,948 dual-core computer chips and 12,960 cell engines, and it has 80 terabytes of memory housed in 288 connected refrigerator-sized racks. The cost: $100 million. Turek said the computer in a two-hour test on May 25 achieved a "petaflop" speed of sustained performance, something no other computer had ever done. It did so again in several real applications involving classified nuclear weapons work this past weekend. "This is a huge and remarkable achievement," said Turek in a conference call with reporters. A "flop" is an acronym meaning floating-point-operations per second. One petaflop is 1,000 trillion operations per second. Only two years ago, there were no actual applications where a computer achieved 100 teraflops a tenth of Roadrunner's speed said Turek, noting that the tenfold advancement came over a relatively short time. (more excitement at link) WOW.
