News Release!

TSUBAME-KFC is Ranked No. 1 on both Green500 and Green Graph 500 Lists!
News release and details.

Visit Tokyo Tech Booth #1741 at SC13!


The Tokyo Tech Booth, #1741, will showcase the latest results form TSUBAME2.5 as well as ongoing research towards TSUBAME3.0 and beyond to exascale. Tokyo Tech's TSUBAME2.5 is an upgrade to TSUBAME2.0, that was ranked 4th on the Top500 in Nov. 2010 and awarded the "Greenest Production Supercomputer in the World" from the Green500. By replacing all the 4000+ GPUs with the NVIDIA Tesla K20x, TSUBAME2.5 performance is now boosted to 5.76 Petaflops peak in double precision FP, and moreover, 17 Petaflops peak in single precision FP, making it the fastest supercomputer in Japan for that metric. We are also aggressively pursuing various R&D towards TSUBAME3.0 to be deployed late 2015, and in particular TSUBAME-KFC, our prototype for advanced cooling and low power supercomputing, should be very competitive in the Nov. 2013 Green500 rankings.

Tokyo Tech's TSUBAME2.0 is the first Japanese multi-PFlops supercomputer, aggressively utilizing advanced HPC technologies such as GPUs, SSDs, multi-rail Infiniband, and was ranked 4th on the Top500 in Nov. 2010 and awarded the "Greenest Production Supercomputer in the World" from the Green500 in Nov.2010 & Jun.2011. There are tens of petascale applications on TSUBAME2.0, including two applications that won the 2011 Gordon Bell special and honorable mention awards, as well as the 4th-ranked Graph500 run application.
Mid-life kicker TSUBAME2.5 as well as multitudes of systems & application research are underway towards TSUBAME3.0 and exascale. Visit the booth to find out!


The TSUBAME e-science journal showcases many exciting ongoing projects from a wide range of disciplines. In the latest issue to be published in 18th Nov, we focus on the TSUBAME2.5 evolution and large-scale GPU applications. The researchers have been able to achieve astounding breakthroughs and gain new insight into today's most challenging HPC problems, all made possible by the power of TSUBAME.
