US regains supercomputer crown from Chinese

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.
