Cray Jaguar Takes Top Supercomputer Spot from IBM Roadrunner

After more than a year as the world’s fastest supercomputer, IBM’s Roadrunner system was knocked down to the second spot by Cray’s Jaguar. Cray’s XT5 system got a boost when the computer maker swapped out the quad-core AMD Opterons for the six-core “Istanbul” chips, ramping up the power to more than 224,000 processing cores. Sun and SGI also were represented in the top 10 of the Top500 list of the fastest systems.
