Tokyo Tech's TSUBAME 2.0 will officially be named the fastest Japanese supercomputer next month, with a raw performance of 2.4 petaflops that surpasses the total floating point operations per second capability of all other government and academic supercomputers currently in Japan.

TSUBAME is part of a new generation of general-purpose graphics processing unit-powered systems penetrating large research institutions across the globe. First-generation TSUBAME systems were built with Sun Microsystems equipment, but Tokyo Tech turned to Hewlett-Packard to co-design the second-generation TSUBAME along with NEC.

TSUBAME 2.0 is one-quarter the size and will consume about one-quarter the power of Oak Ridge Laboratory's Jaguar supercomputer while having roughly the same peak performance.

TSUBAME project leader and professor Satoshi Matsuoka says the supercomputer will be particularly useful for real-world applications in climate and weather projections, biomolecular simulation, tsunami modeling, CFD codes, and other scientific codes.
