Tianhe to run 1 quintillion per second

China's supercomputer can achieve high speed ahead of US, Japan peers

Scientists have set an ambitious target for China's Tianhe-3 supercomputer to meet by 2020, the goal of making a quintillion calculations per second.

The supercomputer is expected to hit the speed - which can also be expressed as a billion billions, or 1 followed by 18 zeros - ahead of the United States and Japan, where their supercomputer scientists are also beefing up efforts to meet the ambitious goal.
