Tsubame 2 supercomputer 3.4X more efficient

NVIDIA championed a milestone for supercomputers Wednesday with the launch of a new supercomputer cluster that focuses on eco-friendly power. Tsubame 2.0, at the Tokyo Institute of Technology, uses a mix of traditional processors with Tesla cards to dramatically step up the potential maximum performance without having to ramp up the energy it uses. Although it can calculate at up to 1.19 petaflops, it uses a comparatively modest 1.2MW of power, making it 3.4 times more efficient at getting work done than Los Alamos National Laboratory's processor-only Cielo Cray.

Tokyo University to get 2nd fastest supercomputer

The Tokyo Institute of Technology revealed on Wednesday that its next-generation supercomputer will start operation in the fall. Called Tsubame 2.0, it will use 2,816 six-core, 2.96GHz Xeon 5600 processors combined with 4,224 of NVIDIA's Tesla M2050 general-purpose GPUS to top 2.39 petaflops. It should rank second in the Top 500 ranking as of June 2010 and will also be the first petaflop supercomputer in Japan.
