China's new supercomputing system, Sunway-TaihuLight, was named the world's fastest computer at the International Supercomputing Conference in Germany in last Month.
The National Supercomputing Center was also unveiled Monday in Wuxi, east China's Jiangsu Province, where the new-generation supercomputer is installed.
With processing capacity of petaflops (PFlops) per second, which means it can perform quadrillions of calculations per second at peak performance, Sunway-TaihuLight is the first supercomputer to achieve speeds in excess of 100 PFlops.
The computing power of the supercomputer is provided by a China-developed many-core CPU chip ==
The Five-hundred-meter Aperture Spherical Telescope (FAST) is an Aricibo-type telescope. It is funded by the National Development and Reform Commission (NDRC) and managed by the National Astronomical observatories (NAOC) of Chinese Academy of Sciences (CAS), with the government of Guizhou province as a cooperation partner.
When it is completed in 2016 , the five hundred meter aperture spherical telescope (FAST) will be the world's largest, overtaking Puerto Rico's Arecibo Observatory, which is 300 meters in diameter
