China is planning to develop a prototype of an exascale computer, considered the next frontier of supercomputers, by the end of 2017, according to a developer Tuesday. “A complete computing system of the exascale supercomputer and its applications can only be expected in 2020, and will be 200 times more powerful than the country’s first petaflop computer Tianhe-1, recognized as the world’s fastest in 2010,” said Zhang Ting, application engineer with the Tianjin-based National Supercomputer Center, when attending the sixth session of the 16th Tianjin Municipal People’s Congress Tuesday.
