In a ranking of the 500 fastest scientific computers Chinese machines gained the top and second spot.
Sunway TaihuLight is the new No. 1 system with 93 petaflop/s ( quadrillions of calculations per second) and 10,649,600 computing cores comprising 40,960 nodes. Sunway TaihuLight is twice as fast and three times as efficient as Tianhe2. The peak power consumption under load (running the HPL benchmark) has lowered from 17.8MW to 15.37 MW, or 6 Gflops/Watt.
The machine is powered by a new locally developed ShenWei processor and custom interconnect, ending the assumption that China would have to rely on Western technology to compete effectively in supercomputing.
TaihuLight is currently up and running at the National Supercomputing Center in the a manufacturing and technology hub Wuxi, a city with two-hour’s drive west of Shanghai.
Rounding out the Top 10 are Titan, a Cray XK7 system installed at the Department of Energy’s (DOE) Oak Ridge National Laboratory; 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.
