China wants to deliver an exascale computing system by 2020, three years ahead of the U.S. plan to achieve the same goal.

The system, being developed at China's National University of Defense Technology, will be called Tianhe-3, following a naming pattern that began in 2010 when China announced the Tianhe-1, its first petaflop-scale system.

However, it is unclear if China will be able to achieve its plan to develop an exascale system by 2020, as U.S. experts believe the power required to run such a system--20 to 30 megawatts--will not be possible until 2023 at the earliest. T

he first stage of a future Chinese exascale system likely will be peak exaflop performance, and then a Linpack test making it eligible for ranking on the Top 500 supercomputing list, according to IDC analyst Steve Conway. However, he notes the measure "that counts most, but will be likely be celebrated least, is sustained exaflop performance on a full, challenging 64-bit application."

Conway says that third stage probably will not happen until the 2022 to 2024 time frame, similar to the one the U.S. has set for its own sustained exascale performance.
