Your computer just got more sluggish -- at least by comparison. The New York Times reports that a supercomputer at Los Alamos National Laboratory just broke the petaflop barrier, "processing more than 1.026 quadrillion calculations per second," according to the story. At $133 million, the machine is double the speed of the previous fastest supercomputer and is based in large part on the Cell processors that first powered the Sony PlayStation 3.
