SC10—NEW ORLEANS—Nov. 18, 2010—The “Green500” list of the world’s most energy-efficient supercomputers was released today, revealing that the only petaflop systems in the top 10 are powered by NVIDIA® Tesla™ GPUs.

Of these GPU-powered petaflop systems, Tsubame 2.0, from Tokyo Institute of Technology (Tokyo Tech), was ranked number two; and Tianhe-1A, the world’s fastest supercomputer from National Supercomputer Center in Tianjin, was ranked number 10.

“The rise of GPU supercomputers on the Green500 signifies that heterogeneous systems, built with both GPUs and CPUs, deliver the highest performance and unprecedented energy efficiency,” said Wu-chun Feng, founder of the Green500 and associate professor of Computer Science at Virginia Tech.

GPUs have quickly become the enabling technology behind the world’s top supercomputers. They contain hundreds of parallel processor cores capable of dividing up large computational workloads and processing them simultaneously. This significantly increases overall system efficiency as measured by performance per watt. “Top500” supercomputers based on heterogeneous architectures are, on average, almost three times more power-efficient than non-heterogeneous systems.

Two other Tesla GPU-based systems made the Top 10 and Tesla GPU-based systems installed at CSIRO in Australia and National Supercomputer Center in Shenzhen were also ranked 11 and 12 respectively.

The complete Top 10 list (with Tesla GPU-powered systems in bold face):

Rank Site Linpack Perf. # of Tesla GPUs Megaflops per watt
1 IBM Research 653 TeraFlops n/a 1684 Mflops/watt
2 GSIC Center, Tokyo Tech 1.192 Petaflops 4200 948 Mflops/watt
3 NCSA 33.6 Teraflops 128 933 Mflops/watt
4 RIKEN AICS 58 Teraflops n/a 828 Mflops/watt
5 Forschungszentrum Juelich 45 Teraflops n/a 773 Mflops/watt
6 Universitaet Regensburg 45 Teraflops n/a 773 Mflops/watt
7 Universitaet Wuppertal 45 Teraflops n/a 773 Mflops/watt
8 Universitaet Frankfurt 94 Teraflops n/a 741 Mflops/watt
9 Georgia Institute of Technology 64 Teraflops 360 677 Mflops/watt
10 NSC Tianjin 2.507 Petaflops 7168 635 Mflops/watt

Many of the leaders of those supercomputing centers recognized by the Green500 organization are present this week at the SC’10 conference in New Orleans. They made the following comments:

Prof. Satoshi Matsuoka of Tokyo Tech said: “Our goal with Tsubame 2.0 was to deliver petaflop performance in as small a power envelope as possible. Moving to Tesla-based GPU supercomputers was the only way to achieve this.”

Dr. Jeffrey Vetter of Georgia Tech and Oak Ridge National Laboratory said: “Keeneland is a proving ground for software development spanning research and industry. Through its use of GPUs and heterogeneous architectures, we are paving the way to energy-efficient exascale computing.”

Dr. Gareth Williams of Australia’s CSIRO said: “With the help of GPUs, we have succeeded in developing the fastest, most efficient supercomputer in Australia. With this kind of computational resource, we will be able to dramatically advance the pace of our research.”

“The high performance per watt of Tesla GPUs has made them the architecture of choice for modern supercomputing, as evidenced by GPU supercomputers being the only petaflop-capable systems in the Top 10,”said Andy Keane, general manager, Tesla business at NVIDIA. “We congratulate all the centers that have been recognized for their work in this year’s Green500.”
