United States grabs supercomputing lead

The United States is back atop the supercomputing peak, at least for now. On Friday, engineers at Oak Ridge National Laboratory in Tennessee fired up Summit, a new supercomputer capable of carrying out 200 quadrillion calculations per second, or 200 petaflops, Wired reports. That’s roughly 1 million times the speed of a standard laptop, and twice that of China’s top machine, the Sunway TaihuLight, which has claimed the top spot since June 2013. Summit may not be king of the hill for long. China, the European Union, Japan, and the United States all have their sights set on making the first “exascale” machine, with 1000 petaflops of computing power.
