The Green500 might not be quite as well known as the Top500, but it's no less of an honor to be counted among the world's most energy efficient supercomputers. NVIDIA is tooting its own horn for making it on to the list for the second year in a row as part of the "greenest" petaflop machine. The Tsubame 2.0 at the Tokyo Institute of Technology's Global Scientific Information Center is powered by Intel's Xeon CPUs, but NVIDIA's Tesla general purpose GPUs do a vast majority of the number crunching, allowing it to deliver 1.19 petaflops of performance while consuming only 1.2 megawatts. That's roughly 958 megaflops per watt, a huge increase over the most efficient CPU-only super computer, the Cielo Cray, which gets only 278 megaflops per watt. The Tsubame 2.0 isn't the greenest machine on the planet though, that honor belongs to IBM's BlueGene which takes the top five spots on the Green500. Still, number ten ain't bad... right? Check out the PR after the break.
