China Overtakes US in Number of Supercomputers

For the first time in history, China has overtaken the United States in the number of supercomputers.  Currently, China has a total of 202 of the world’s 500 fastest computers, up from 159 half a year ago. The number of US supercomputers has dropped to 144.

The world’s most powerful computer is located in China. The Sunway  TaihuLight ,  at Wuxi can do 93 quadrillion calculations per second. The fastest US computer, the Titan, is ranked fifth while Europe’s speediest computer is Switzerland’s Piz Daint, ranked third.

Supercomputers are machines that occupy entire buildings and use the combined power of thousands of processors. They are used to carry out special tasks that involve a huge number of calculations.  Among them are weather forecasts and climate studies, as well as strategic tasks like nuclear weapons simulations.

Chinese supremacy in the world of supercomputing reflects the country’s  investment in research and development. One-fifth of the money used on research and development around the world is spent in China.

On the other side, many Chinese systems have been created to earn money. Processing power is rented to other national and international companies.

For years the speed of supercomputers has steadily increased although since 2012 this increase has slowed down.
