A Chinese supercomputer called Sunway TaihuLight now ranks as the world's fastest, nearly tripling the previous supercomputer speed record with a rating of 93 petaflops per second. That's 93 quadrillion floating point operations per second (or 93 million billion).
Sunway TaihuLight surpassed another Chinese supercomputer, Tianhe-2, which had been the world's fastest for three consecutive years with speeds of 33.9 petaflop/s, according to the latest Top500.org ranking released today. Top500 rankings are based on the Linpack benchmark, which requires each cluster "to solve a dense system of linear equations."
"Sunway TaihuLight, with 10,649,600 computing cores comprising 40,960 nodes, is twice as fast and three times as efficient as Tianhe-2," the Top500 announcement said. Sunway TaihuLight is one of the world's most efficient systems, with "peak power consumption under load (running the HPL benchmark)... at 15.37MW, or 6 Gflops/Watt."
