Cray Inc., maker of the XT5-HE supercomputer at the heart of Jaguar, says it has inked a deal with ORNL to overhaul the Department of Energy computer with thousand of graphics processors from NVIDIA as well as chips from Advanced Micro Devices. The tune-up will push the peak performance beyond K Computer's current capacity, putting ORNL's computer at the top of the TOP500 for the first time since last year. After the overhaul, Jaguar will be renamed Titan.
