LIAO Xiaohan, Deputy Director of Department of High Technology, part of the Ministry of Science and Technology, recently visited the SEHNTENG 6800 Supercomputer developed by LEGEND Group at a network center in the Chinese Academy of Sciences. He was briefed of the latest development of high performance computers and associated core software.
High performance computers and associated core software, a major special project under the National 863 Program, has the following strategic objectives: develop a high performance computer; build a high performance computer environment; program a proprietary grid software; and establish two or three major application grids to meet urgent demands of scientific research, economic construction, social development, and national defense.
At present, SHUGUANG 4000A, a super server, has registered a peak speed of 11.2 trillion times per second, with a linpack sustainability reaching 8.1 trillion times per second, and a general efficiency score at 71.56%. As major grid equipment for 863 CNGrid, the server is homed at Shanghai Super Computation Center. In June 2004, it was ranked 10th place among top 500 high performance computers in the world. The SHENTENG 6800 Supercomputer, developed by LEGEND Group, has recorded a peak speed at 5.324 trillion times per second, with a linpack sustainability of 4.183 trillion times per second, and a general efficiency score at 78.5%. The system, housed at CAS Computer Network Information Center, was rated 14th place among top 500 high performance computers in November 2003.
CNGrid GOS v1.0, a grid software, was published in December 2003. The version has basic computation grid functions, including service packaging, assignment coordination, and resources management. As of November 30, 2004, the CNGrid software has been installed on all grid knots, making the software a dominating grid program in the country.
High performance computer and grid software project, supported by a special plan for grid, has led to the construction of CNGrid. Equipped with home developed high performance grid computers, CNGrid is made up of 8 knots, including CAS network center (core knot), Shanghai Super Computation Center, Tsinghua University, Institute of Applied Physics and Computational Mathematics, Xi?痑n Jiaotong University, the University of Science and Technology of China, National University of Defense Technology, and Hong Kong University. These knots have formed up an open grid environment, supporting grid environment based operation and development of application grids, using proprietary grid software. In an attempt to support resources sharing and teamwork, CNGrid has become an experimental bed for scientific research, technology development, and applications and demonstration. |
