China is planning to develop pre-exaFLOP prototype supercomputer in 2017 which is preparation for an exaFLOP supercomputer in 2020.
According to “Открытые системы”, the first pre-exascale machine is being created by NUDT and will use ARM-based processors and will be deployed at the national supercomputer center in Tianjin where the Tianhe-1A CPU-GPU hybrid was deployed in 2010 and gave China its first top spot on the Top 500 rankings of supercomputers.
Note that, the first exaflop supercomputer is scheduled for launch in 2023, in the US.
