The Sunway TaihuLight China has 10.65 million compute cores built entirely with Chinese microprocessors and there is not a single US computer which matches it. The TaihuLight sticks two fingers up at the US for banning the sale of Intel’s Xeon chips to China.
The super computer has a theoretical peak performance is 124.5 petaflops and it is the first system to exceed 100 petaflops.
TaihuLight is installed at China’s National Supercomputing Center in Wuxi, uses ShenWei CPUs developed by Jiangnan Computing Research Lab in Wuxi. The operating system is a Linux-based Chinese system called Sunway Raise.
It is used for advanced manufacturing, earth systems modelling, life science and big data applications.
The US initiated this ban because China, it claimed, was using its Tianhe-2 system for nuclear explosive testing activities. The US stopped live nuclear testing in 1992 and now relies on computer simulations. Critics in China suspected the U.S. was acting to slow that nation’s supercomputing development efforts.
The fastest US supercomputer, number 3 on the Top500 list, is the Titan, a Cray supercomputer at US Dept. of Energy’s Oak Ridge National Laboratory with a theoretical peak of about 27 petaflops.
