Supercomputer TSUBAME

"Everybody's Supercomputer" TSUBAME Leading the New Generation

The Global Scientific Information and Computing Center is one of the leading supercomputer centers in the world, leading R&D and operations of one of the world's top supercomputer, TSUBAME. In November 2010, in partnership with several industry partners, we developed, installed and commenced the operation of the TSUBAME2.0 supercomputer. TSUBAME2.0 sports a heterogeneous architecture, combining the new-generation vector processor GPUs (Graphics Processing Unit) with high performance CPUs (Central Processing Unit) at large scale. Supercomputer-based simulation is now playing pivotal roles in majority of areas in science and technology, being regarded as the "third pillar" of methodologies alongside traditional theory and experiments. TSUBAME2.0 is not only being used widely as a centerpiece simulation infrastructure within Tokyo Institute of Technology, but also provides petaflops-scale supercomputing capabilities nationwide, being one of the leading resource centers of the Japanese High Performance Computing Infrastructure (HPCI) under the Ministry of Education, Culture, Sports, Science and Technology (MEXT). Also, over 100 commercial companies have used TSUBAME to date in our industry usage programs, and as such TSUBAME contributes significantly to Japan's industrial innovations. Finally, TSUBAME2.0, as "Everyone's Supercomputer," plays a major educational role for future generations, being used in training of Tokyo Tech. students in both Information Technologies and advanced simulations, as well as hosting various supercomputing contests including the nationwide competition for high school students.

TSUBAME 2.0 has a peak performance of 2.4 Petaflops (double precision) and 4.8 Petaflops (single precision), the first supercomputer in Japan to exceed 1 Petafop performance. Such performance was attainable due to various innovations in achieving low electric power consumption and low cost, including the massive use of GPUs. In November 2010, it was ranked fourth in the world in the ranking of supercomputer performance "The Top 500," and second in the world in "The Green 500," that ranks the ratio of performance per unit of power consumption (MegaFlops/Watt). In 2011, it was also ranked third in the world in the "The Graph 500," which is a ranking of big data processing performance, in particular large-scale graphs. In November 2012, it won the ACM Gordon Bell award, which one of the highest honors in the supercomputing field, for achieving highest performance and fast time-to-solution for a real, practical application (Phase-Field Simulation for Dendritic Solidification). It has won a number of other international and domestic awards as well.

Our GSIC Center has a continuous, on-going effort to evolve the performance of TSUBAME. In September 2013, all of the GPUs installed in the TSUBAME 2.0 will be replaced with latest versions, and as a result, the peak performance will improve to 5.7 PFLOPS (double precision) while reducing power consumption. In single-precision, TSUBAME2.0 will embody peak performance of 17 PFLOPS, which will surpass the "K Computer" to become the fastest supercomputer in Japan (but not in Linpack/Top500). Also GSIC, in preparation for future TSUBAME 3.0, 4.0, and beyond to exascale, is constructing an experimental facility called "TSUBAME-KFC" to develop innovative methods for power-saving and efficient cooling of supercomputers, as well as actively collaborate with research institutes and industries worldwide, in topics such as fault tolerance of large-scale systems, large-scale "big-data" processing for scientific data,, and massively parallel programming and applications in the heterogeneous, many-core computing.
