I.B.M. to Build Supercomputer Powered by Video Game Chips

The Department of Energy said Wednesday that it had awarded I.B.M. a contract to build a supercomputer capable of 1,000 trillion calculations a second, using an array of 16,000 Cell processor chips that I.B.M. designed for the coming PlayStation 3 video game machine.
The Roadrunner will use the Sony Cell Broadband Engine as a specialized processor, with a corresponding array of Advanced Micro Devices Opteron microprocessors. This kind of hybrid design is increasingly being used as designers scramble to reach ever-greater computing speeds.
