Sunway TaihuLight supercomputer of China was declared as world’s fastest supercomputer, it can compute 93 million-billion calculations per second. As of June 2016, it is ranked number one in the TOP500 list as the fastest supercomputer in the world. Important to mention here that this is first time any Chinese supercomputer has won this award without using any U.S. processors or technology. Second place in the list has been also secured by another supercomputer of China named Tianhe-2. Supercomputer of US Department of Energy (DOE) named Titan has been placed at third rank. China now has 171 computers on the list, an increase from last year’s 168.
The Top500 list is compiled on the basis of Linpack benchmark performance and is considered one of the most authoritative rankings in the world of supercomputers.
Specification of Sunway TaihuLight
- The Sunway TaihuLight uses a total of 40,960 Chinese-designed SW26010 manycore 64-bit RISC processors based on the Sunway architecture.
- Each processor chip contains 256 processing cores, and an additional four auxiliary cores for system management that are also RISC cores just more fully featured, for a total of 10,649,600 CPU cores across the entire system.
- The processing cores feature 64 KB of scratchpad memory for data (and 16 KB for instructions) and communicate via a network on a chip, instead of having a traditional cache hierarchy.
- The system runs on its own operating system, Sunway RaiseOS 2.0.5, which is based on Linux. The system has its own customized implementation of OpenACC 2.0 to aid the parallelization of code.

The Top500 list is compiled on the basis of Linpack benchmark performance and is considered one of the most authoritative rankings in the world of supercomputers. TaihuLight made its appearance in June, replacing the former champion, Tianhe-2, also a Chinese system but built based on Intel chips. TaihuLight is capable of performing 93 million billion calculations per second (petaflop/s).
