The U.S. Department of Energy reports the world’s fastest computer, a hybrid supercomputer codenamed “Roadrunner,” can compute 1,000 trillion operations per second.

The machine was designed by IBM and uses Cell Broadband Engine chips, technology originally developed for video game platforms. “Roadrunner” was built for the Department of Energy’s National Nuclear Security Administration and will be housed at Los Alamos National Laboratory in New Mexico. “Roadrunner’s” primary duty will be to help ensure that the U.S. nuclear weapons stockpile is safe and reliable without nuclear testing, by running complex nuclear weapons calculations that give scientists critical data.
