US regains supercomputer crown from Chinese2018-06-11 12:34 by Daniela
The US now has the world's fastest supercomputer. For five years, China had the world's fastest computer. But the United States retook the lead thanks to a machine, called Summit, built for the Oak Ridge National Laboratory in Tennessee.
Summit, built by IBM, occupies floor space equivalent to two tennis courts, and slurps 4,000 gallons of water a minute around a circulatory system to cool its 37,000 processors. It is made up of rows of black refrigerator-size units that weigh a total of 340 tons. Summit's speeds are stunning.
Oak Ridge says its new baby can deliver a peak performance of 200 quadrillion calculations per second (that's 200 followed by 15 zeros) using a standard measure used to rate supercomputers, or 200 petaflops. That's about a million times faster than a typical laptop, and nearly twice the peak performance of China's top-ranking Sunway TaihuLight.
Supercomputers like Summit, which cost $200 million in government money to build, can accelerate the development of technologies at the frontier of computing, like artificial intelligence and the ability to handle vast amounts of data.
