IBM's Roadrunner is the new fastest computer on earth, the first to break the petaflop barrier (1,000 trillion floating point operations per second). It's at the Los Alamos National Laboratory working on nuclear weapons simulations.
"Roadrunner uses 3.9 megawatts of power, which Grice noted is enough to power 39,000 100-watt light bulbs. It has 6,948 dual-core Opterons on IBM LS21 Blades, as well as 12,960 Cell processors on IBM QS22 blades. The machine, which has 80 terabytes of memory, has 296 IBM BladeCenter H racks. It takes up 6,000 square feet, uses 57 miles of fiber optic cable and weighs in at 500,000 pounds."
