| Abstract: | This paper presents an overview of TianHe-1A (TH-1A) supercomputer, which is built by National University of Defense Technology
of China (NUDT). TH-1A adopts a hybrid architecture by integrating CPUs and GPUs, and its interconnect network is a proprietary
high-speed communication network. The theoretical peak performance of TH-1A is 4700 TFlops, and its LINPACK test result is
2566 TFlops. It was ranked the No. 1 on the TOP500 List released in November, 2010. TH-1A is now deployed in National Supercomputer
Center in Tianjin and provides high performance computing services. TH-1A has played an important role in many applications,
such as oil exploration, weather forecast, bio-medical research. |
