Intel’s Xeon Phi Powered Beacon is World’s Most Efficient Supercomputer

The Green500 ranks the most energy-efficient supercomputers in the world, and the latest list has an Intel-powered system at the top: “Beacon”, a supercomputer located at the National Institute for Computational Sciences (NICS), is the world’s most efficient supercomputer.

Notably, Beacon uses Intel’s new Xeon Phi 5110p coprocessors(running its MIC architecture) along with Intel Xeon E5-2670 chips to drink just 44.89kW of power while offering almost two-and-a-half billion floating-point operations per second per watt (2.49 GFlops/Watt) and hits 112,200 gigaflops at peak performance.

Intel has to be feeling pretty good about that ranking, because it firmly believes that its Xeon Phi coprocessors using parallel processing are the key to achieving exascale computing, and finding a way to keep energy consumption in check is a huge obstacle to overcome.

It also bodes well for the prospects of one of the next major supercomputers to come online, the Texas Advanced Computer Center’s “Stampede”, which is currently under construction and makes use of the Xeon Phi coprocessors, as well.
