According to a biannual ranking of the world’s 500 fastest supercomputers, called the Top500, Sunway’s TaihuLight maintains the lead as the No. 1 system for the fourth time, with a performance of 93.01 petaflops. Tianhe-2, or Milky Way-2, is still the No. 2 system at 33.86 petaflops. Intel chip-based Tianhe-2 had topped the list for three years until it was displaced in November 2015 by TaihuLight, which was built entirely by using processors designed and made in China. No. 3 is Switzerland’s Piz Daint, which is also the most powerful supercomputer in Europe. A new system in Japan, called Gyoukou, is the No. 4, pushing Titan, the top U.S system, to the No. 5.
