Sunway TaihuLight, with 10,649,600 computing cores comprising 40,960 nodes, is twice as fast and three times as efficient as Tianhe-2, which posted a LINPACK performance of 33.86 petaflop/s. The peak power consumption under load (running the HPL benchmark) is at 15.37 MW, or 6 Gflops/Watt. This allows the TaihuLight system to grab one of the top spots on the Green500 in terms of the Performance/Power metric. Titan, a Cray XK7 system installed at the Department of Energy's (DOE) Oak Ridge National Laboratory, is now the no. 3 system. It achieved 17.59 petaflop/s.
Rounding out the Top 10 are Sequoia, an IBM BlueGene/Q system installed at DOE's Lawrence Livermore National Laboratory; Fujitsu's K computer installed at the RIKEN Advanced Institute for Computational Science (AICS) in Kobe, Japan; Mira, a BlueGene/Q system installed at DOE's Argonne National Laboratory; Trinity, a Cray X40 system installed at DOE/NNSA/LANL/SNL; Piz Daint, a Cray XC30 system installed at the Swiss National Supercomputing Centre and the most powerful system in Europe; Hazel Hen, a Cray XC40 system installed at HLRS in Stuttgart, Germany; and Shaheen II, a Cray XC40 system installed at King Abdullah University of Science and Technology (KAUST) in Saudi Arabia is at no. 10.
The latest list marks the first time since the inception of the TOP500 that the U.S is not home to the largest number of systems. With a surge in industrial and research installations registered over the last few years, China leads with 167 systems and the U.S. is second with 165. China also leads the performance category, thanks to the no. 1 and no. 2 systems.
The European share of 105 systems - compared to 107 in November 2015 - has fallen and is now lower than the dominant Asian share of 218 systems, up from 173 in November. Germany is the clear leader in Europe with 26 systems followed by France with 18 and the UK with 12 systems. In Asia, Japan trails China with 29 systems - down from 37.
Cray continues to be the clear leader in the TOP500 list in total installed performance share with 19.9 percent - down from 25 percent. Thanks to the Sunway TaihuLight system, the National Research Center of Parallel Computer Engineering & Technology takes the second spot with 16.4 percent of the total performance - with just one machine. IBM takes the third spot with 10.7 percent share, down from 14.9 percent six months ago. HPE is third with 12.9 percent, down from 14.2 percent six months ago.
For the first time, the data collection and curation of the Green500 project is now integrated with the TOP500 project. The most energy-efficient system and no. 1 on the Green500 is Shoubu, a PEZY Computing/Exascaler ZettaScaler-1.6 System achieving 6.67 GFfops/Watt at the Advanced Center for Computing and Communication at RIKEN in Japan.
