Prof. Li Guojie graduated from Peking University in 1968, and received M.E degree from Chinese Academy of Sciences in 1981 and Ph. D in Computer Science from Purdue University in 1985. During 1985～1986, he carried out postdoctoral research at the University of Illinois, USA, and came back to China for work in 1987. He was a researcher of Institute of Computing Technology in 1989, director of National Research Center for Intelligent Computing Systems in 1990 and vice leader of the expert panel on intelligent computer of National 863 Program, and he was elected member of Chinese Academy of Engineering in 1995 and member of Third World Academy of Sciences in 2002. At present, he is the director of Institute of Computing Technology, Chinese Academy of Sciences.
Prof. Li Guojie is mainly engaged in research in the fields such as parallel processing, computer architecture, and artificial intelligence etc. He has published over 100 academic papers and is the coauthor of 4 monographs in English. In recent years, he has successfully developed Dawning-1 parallel computer, Dawning-1000 large-scale parallel computer and Dawning-Tianyan series of computer. He received the first and second prize of the National Sci-Tech Advance Award and the Science & Technology Progress Award of He-Liang-He-Li Fund.
Li Guojie is currently the director of Information and Electronics Division of Chinese Academy of Engineering, president of China Computer Society, a delegate of the National People's Congress, vice director of the expert panel on information of National 863 Program, member of the Advisory. Committee for the State Informatization, vice leader of the research group for industrialization of strategic high technologies and high and new technologies in medium and long-term Sci-tech development planning, editor-in-chief of Journal of Computer Science and Technology and so on.
"Important Research Directions Changing Information Scientific Technology"
In the past several decades, the development of information technology mainly focused on high efficiency and large-scale production, with less focus on low energy consumption, low cost, usability, reliability, safety and individuation. In the first half of 21st century, the main stream of information technology development is popularization, application and benefit to the public. The popularization of information technology may take longer time and need technical innovations of higher levels than those of electricity technology. Current information industry is a high energy consumption industry, and there is still large space for low energy consumption information technology to develop.
This report points out that in the first half of 21st century, a new information science reform with characteristics of high-efficiency calculation and digital simulation will arise. Breakthroughs of scientific discovery may lead to a new technical reform in the last half of 21st century. A popular view at present that “computer simulation is the third way of scientific research other than experiment and theory research” is not quite proper. The trend of cross science development in 21st century is to put calculation into whole stages of scientific research, which will form a new form of scientific research. Within several decades in the future, simulative calculation may be an important research direction of computer scientists.
