NEW ORLEANS, LA--(Marketwire - November 18, 2010) - SC10 -- The "Green500" list of the world's most energy-efficient supercomputers was released today, revealed that the only petaflop system in the top 10 is powered by NVIDIA® Tesla™ GPUs.
"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.
Three other Tesla GPU-based systems made the Top 10. The National Center for Supercomputing Applications (NCSA) and Georgia Institute of Technology in the U.S. and the National Institute for Environmental Studies in Japan secured 3rd, 9th and 10th respectively. Tesla GPU-based systems also secured 11th, 12th and 13th; CSIRO in Australia, Tianhe-1A in Tianjin and Nebulae in Shenzhen, China.
