Sunway TaihuLight supercomputer makes its appearance

The Sunway TaihuLight System [1] is very impressive with over 10 million cores and a peak performance of just over 125 Pflop/s. The Top500 list has the Sunway TaihuLight as the fastest computer. The Sunway is almost three times (2.75 times) as fast and three times as efficient as the system it displaces in the number one spot. In fact, the sum of the performance for computers in position 2 through 7 is just barely greater than the performance of the Sunway system. The HPL Benchmark results at 93 Pflop/s or 74% of theoretical peak performance is impressive, with an efficiency of 6 Gflops per Watt; this is the highest efficiency of all the top computers. The HPCG benchmark performance at only 0.3%of peak performance shows the weakness of the Sunway TaihuLight architecture with slow memory and modest interconnect performance.
