RoadRunner – The first Petaflop Supercomputer - 2008

The world’s fastest supercomputer atLos Alamos National Laboratory is the                                                          "petaflop barrier" of 1,000 trillion                                                        operations per second. Compared to                                                    most traditional supercomputers today,                                               hybrid design of the supercomputer at                                                         Los Alamos delivers world-leading                                                       energy efficiency, as measured in                                                             flops per watt.

Designed by IBM, the world's first"hybrid“supercomputer introduces the use of the IBM PowerXCell™ 8i chip, an enhanced Cell Broadband Engine™ (Cell/B.E.™) chip—originally developed for video game platforms—in conjunction with x86 processors from AMD™. The supercomputer was built for the U.S. Department of Energy's National Nuclear Security Administration and is housed at Los Alamos National Laboratory in New Mexico
