TH-1 (Milky Way): China's First Petaflop-class Supercomputer
Abstract The Tianhe-1 (TH-1) supercomputer has been built by National University of Defense Technology (NUDT) in 2009. TH-1 could achieve a theoretical peak performance of 1.206 petaflops and is ranked the 5th in the current Top500 supercomputer list. The TH-1 system will be hosted at the National Supercomputer Center in Tianjin to provide high performance computing service for the Tianjin area and the northeast of China, particularly for solving the computing problems in data processing for petroleum exploration and the simulation of large aircraft designs. The TH-1 system adopted a hybrid design with Intel Xeon processors and AMD GPUs. This calls for a special dynamic load balance technique for allocating the tasks between CPU and GPU, and several accompanying optimization methods, including software-pipelining techniques for overlapping the execution of GPU and the transmission of data between GPU and CPU, and affinity-scheduling techniques for reducing the performance fluctuation by utilizing processor cores' computing and controlling ability. In this talk, Prof. Lu will introduce the main features of TH-1 system. The optimization methods used to achieve a better result of LINPACK benchmark will also be discussed.
BiographyProf. Lu received a PhD in Computer Science from the National University of Defense Technology in 1999. He is currently a professor and vice director of Institute of Computer in NUDT, the associated chief designer of TH-1 super computer. His research interests include system software for high performance parallel systems, embedded system software and runtime system.
Dawning Roadmap for Cloud Computing Business
Biography Ulysses Xiaoyu Li is the CTO of Dawning Information Industry Co., Ltd. Before he joined Dawning to lead its technology direction for this China's premier company for supercomputers and enterprise servers, he has been a Silicon Valley high-tech entrepreneur who returned to his motherland with his pioneering supercomputer startup Clustars. As a veteran system architect and Internet technologist, he has held various technology or managerial positions in both industries and academics in the US for more than 15 years. After graduate school in the US, Ulysses Li started his career as an Internet expert at Superconducting Super Collider Lab. Later he had a brief technical consulting service to Chase Manhattan Bank in Wall Street and then he worked at Stanford University as its principal system developer for quite a few years. He then joined Southwestern Bell Internet Services (now a part of the new AT&T) and he was leading its Internet engineering team as chief architect. Later on, he played various key technology roles at quite a few high-tech startups in the Silicon Valley before eventually he founded his own supercomputing company. Ulysses Li graduated from Beijing Normal University with a B.S. degree in astrophysics in 1983 and received his M.A. degree from University of Texas at Austin in 1990.
Issues in High End Computing Systems
Biography Prof Mingfa Zhu is a professor with Beihang University, and a Chief Scientist with the Lenovo Group. His research interests cover high performance computer architectures, parallel processing, and bioinformatics. Prof Zhu obtained his PhD in Computer Engineering from Michigan State University in Computer Engineering in 1985. He was one of the main architects for a series of high performance computers such as Dawning and Lenovo Shenteng.
