It‚??s been a week full of awards, and a Gordon Bell Prize, for the Tokyo Tech (http://www.gsic.titech.ac.jp/en) GPU supercomputer team at SC11 (http://sc11.supercomputing.org/).

The team‚??s Tsubame 2.0 supercomputer was recognized as the most energy-efficient petaflop scale supercomputer (http://pressroom.nvidia.com/easyir/customrel.do?easyirid=A0D622CE9F579F09&version=live&prid=825169&releasejsp=release_157&xhtml=true) by the Green500 list (http://www.green500.org/) for the second year in a row. Powered by Tesla GPUs, the Tsubame 2.0 is currently the 5th fastest supercomputer in the world, according to the Top500 list (http://www.top500.org/).

Most notably, the Tokyo Tech won the Gordon Bell Prize at SC11. Known in industry circles as the ‚??Nobel Prize of supercomputing‚??, the prize was awarded to the team for their research on creating lighter, stronger metallic materials (http://pressroom.nvidia.com/easyir/customrel.do?easyirid=A0D622CE9F579F09&version=live&releasejsp=release_157&xhtml=true&prid=826483).

Their research sheds new light on metallic materials‚?? internal microstructural patterns, called dendrites, which determine a material‚??s strength and weight. Rather than relying on computationally limited computer models and simulations, the Tokyo Tech team‚??s petaflop Tsubame 2.0 supercomputer has resulted in breakthrough insights into dendrite formation. In time, these¬*insights will help manufacture metals that can ultimately be used to build more fuel-efficient cars with lighter and stronger metallic materials.

Here‚??s a link (http://www.sim.gsic.titech.ac.jp/English/Research/dendrite.html) to a video of their research, showing dendritic growth in an Al-Si alloy solidification with 4096x1024x4096 mesh on 512 GPUs of the Tsubame 2.0 GPU supercomputer.

The Gordon Bell Honorable Mention was awarded to a research group from¬*CNR, Italy (http://www.cnr.it/sitocnr/Englishversion/Englishversion.html)¬*‚?? working in conjunction with Tokyo Tech and the Tsubame system ‚?? for their work on ‚??Petaflop Biofluidics Simulations On A Two Million-Core System (http://sc11.supercomputing.org/schedule/event_detail.php?evid=gb106).‚??

And, if that‚??s not enough, Tokyo Tech and Tsubame 2.0 also won several additional accolades, including¬*three HPCWire Reader‚??s Choice Awards (http://www.hpcwire.com/hpcwire/2011-11-15/hpcwire_reveals_2011_readers%E2%80%99_and_editors_ choice_awards_at_sc11.html), and¬*two ACM Awards (http://sc11.supercomputing.org/?pg=awards.html)¬*(ACM Special Recognition Award for Perfect Score in Technical Paper (Bautista et. al.), ACM George Michael Memorial HPC Ph.D. Fellowships Honorable Mention (Bautista et. al.)).

Kudos and our warmest congratulations to the Tokyo Tech team.
