NVIDIA Tesla GPU accelerators are powering the world’s two most energy efficient supercomputers, according to the latest Green500 list published last week.
The winning system is Eurora at CINECA, Italy’s largest supercomputing centre, in Casalecchio di Reno. Equipped with NVIDIA Kepler architecture-based GPU accelerators – the highest-performance, most efficient accelerators ever built – Eurora delivers 3,210 MFlops per watt, making it 2.6 times more energy efficient than the best system using Intel CPUs alone (at Météo France). It also greatly surpasses the most efficient Intel Xeon Phi accelerator-based system, Beacon, at the National Institute for Computational Sciences, at the University of Tennessee.
The number two system on the June 2013 Green500 list is the Aurora Tigon supercomputer at the Selex ES facilities Chieti, Italy.
