China to jump supercomputer barrier

China has started to build a new-generation supercomputer that is expected to be 10 times faster than the current world champion.

This year, China is aiming for breakthroughs in high-performance processors and other key technologies to build the world's first prototype exascale supercomputer, the Tianhe-3, said Meng Xiangfei, the director of application at the National Super Computer Tianjin Center. The prototype is expected to be completed in early 2018.

"Exascale" means it will be capable of making a quintillion (1 followed by 18 zeros) calculations per second. That is at least 10 times faster than the world's current speed champ, the Sunway TaihuLight, China's first supercomputer to use domestically designed processors. That computer has a peak speed of 125 quadrillion (1 followed by 15 zeros) calculations per second, he said.
