NVIDIA GPUs Now Power World’s 10 Greenest Supercomputers

The just-published Green500 list of the world’s most energy efficient supercomputers shows that the top 10 systems are all powered by NVIDIA Tesla GPUs The only other architecture ever to have cleanly swept the 10 top spots on the list is IBM’s legendary BlueGene system. Crowned the greenest supercomputer, the Tsubame-KFC system at the Tokyo Institute of Technology, hit a record 4.5 gigaflops per watt. That’s about 25 percent more efficient than the list’s number-two, Cambridge University’s Wilkes, at 3.6 gigaflops per watt. In third place was the system at Japan’s Center for Computational Sciences, at the University of Tsukuba, at 3.5 gigaflops per watt.
