A new ranking shows that for the second year running, the world’s fastest supercomputer is TaihuLight, housed at the National Supercomputing Center in Wuxi, China. Capable of performing 93 quadrillion calculations per second, it’s almost three times faster than the second-place Tianhe-2. And in third spot this year is a newly upgraded device, called Piz Dain, at the Swiss National Supercomputing Centre, which recently had its performance boosted by the addition of Nvidia GPUs.
Sadly for America, the upgraded Piz Dain pushes the Department of Energy’s Titan supercomputer, which is housed at Oak Ridge National Laboratory, into fourth spot. Able to make 17.6 quadrillion number crunches per second, Titan is just a fifth as fast as TaihuLight. In its defense, the U.S. still claims five of the top 10 spots, and it is home to 169 of the supercomputers that make up the fastest 500. China, meanwhile, can only claim 160.
