China is building a 100 petaflops supercomputer

As the U.S. launched what’s expected to be the world’s fastest supercomputer at 20 petaflops (peak performance), China announced it is building a machine intended to be five times faster when it is deployed in 2015, IT World reports.
China’s Tianhe-2 supercomputer will run at 100 petaflops (quadrillion floating-point calculations per second) peak performance, designed by China’s National University of Defense Technology, according to the Guangzhou Supercomputing Center, where the machine will be housed.
Tianhe-2 could help keep China competitive with the future supercomputers of other countries, as industry experts estimate machines will start reaching 1,000-petaflops (1 exaflop) performance by 2018.
The government is aiming for China’s supercomputers to reach 100 petaflops in 2015, and then 1 exaflop (1,000 petaflops), in 2018, according to Zhang Yunquan, a professor at the Institute of Software Chinese Academy of Sciences, who also keeps track of China’s top supercomputers.
