New Supercomputer Champion Crowned at 93 Petaflops

by Sean Michael Kerner

For the first time in history China now has more supercomputers than the U.S.

The crown for the fastest supercomputer in the world has finally been passed from Tiahne-2, after it had held the top spot since June 2013.

The Sunway TaihuLight is now the fastest system on the planet at 93 petaflop/s (quadrillions of calculations per second), nearly three times the power of the 33.86 petaflop/s that enabled Tiahne-2 to dominate for the lastTitan Supercomputer three years.

Sunway TaihuLight was built by the National Research Center of Parallel Computer Engineering & Technology (NRCPC), and it is installed at the National Supercomputing Center in Wuxi, China.

The new supercomputing champion is a massive system, with 10,649,600 computing cores comprising 40,960 nodes.

Not only does the Sunway TaihuLight use more cores than any other system, it is also highly efficient, with peak power consumption under load reported at 15.37 MW, or 6 Gflops/Watt.

Tianhe-2 is now in the number two slot on the Top500 supercomputer list, and for the first time the majority of the Top500 supercomputers in the world are no longer based in the U.S.

Rather China now tops the list at 167 systems, while the U.S has fallen to second place at 165. Europe is home to 105 systems on the Top500 list.

The fastest system in the U.S and number three globally is now the Titan at 17.59 petaflop/s, which is a Cray XK7 system installed at the Department of Energy’s (DOE) Oak Ridge National Laboratory. The Titan was the top supercomputer in the world back in November 2012, at which time it also had a top performance of 17.59 petaflop/s.

Overall, Cray is the top supercomputer vendor on the list in terms of total installed performance share at 19.9 percent. IBM's share stands at 10.7 percent, and HPE is at 12.9 percent. HPE however has the largest total number of systems on the list at 127 systems. In contrast, Cray has 60 and IBM has 38.

455 of the top 500 systems use Intel processors, and 497 use Linux as their operating system.
