June 2016

China maintained its No. 1 ranking on the 47th edition of the TOP500 list of the world’s top supercomputers, but with a new system built entirely using processors designed and made in China. Sunway TaihuLight is the new No. 1 system with 93 petaflop/s (quadrillions of calculations per second) on the LINPACK benchmark.

Developed by the National Research Center of Parallel Computer Engineering & Technology (NRCPC) and installed at the National Supercomputing Center in Wuxi, Sunway TaihuLight displaces Tianhe-2, an Intel-based Chinese supercomputer that has claimed the No. 1 spot on the past six TOP500 lists.

The newest edition of the list was announced Monday, June 20, at the 2016 International Supercomputer Conference in Frankfurt. The closely watched list is issued twice a year.

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.

  • updated performance of 2 systems, as a result many system have changed ranking
