Supercomputing has drawn significant attention from the research and industry communities. The reasons are multidimensional, including the advance of computer technology, the merging of large-scale applications, and needs of national defense. However, designing high performance, high efficiency and high security supercomputers has been proven to be a hard task.

In this talk, Prof. Zhang introduces the TH-1A supercomputer, which was developed by the College of Computer Science of NUDT (National University of Defense Technology). The peak speed of TH-1A is 4700 TFLOPS, the LINPACK test result is 2566 TFLOPS, and it was ranked No. 1 on the TOP 500 list released in November 2010. The architecture which integrates GPUs and CPUs for high-performance parallel comp

uting is exploited for the first time in the world. The whole system consists of two major components: hardware system and software system. For the hardware system, the TH-1A team developed 3 large-scale integrated circuit designs, 4 kinds of nodes, 2 networks, and 15 different PCB boards. Accordingly, the operating system, the compiling system, the parallel programming environment, and the scientific virtualization system were developed for the software system. The TH-1A supercomputer has been used in many applications, including oil exploration, high-end equipment development, bio-medical research, 3D animation, cloud computing, and so on.
