The highest achievement of grid computing in my country - High Performance Computing Environment and Tsinghua ACI System
MONDAY, JUNE 30 2003 3:12 PM At present, grid computing in my country is still in the research stage, academician of the Chinese Academy of Engineering, Li Guojie, director of the Institute of Calculation Technology of the Chinese Academy of Sciences, said when talking about grid, "We must start from now, Because grid technology is most likely to form a standard in recent years. "At present, my country has launched two projects for" national high-performance computing environment "and" advanced computing infrastructure Beijing Pilot Project ", and research on grid computing. These two projects are led by the Chinese Academy of Sciences and Tsinghua University.
National high-performance computing environment
National high-performance computing environment (also known as national computing grid) is a strategic infrastructure of national high-performance computing and information services. It will provide a variety of integrated high performance computing environment and information in various industries nationwide. service. In this project, after the Chinese Academy of Sciences calculates the successfully developed Dawn 2000 and Dawn 3000 super servers, it is also developed the next generation of high-performance computers - Shuguang 4000 and Dawn 5000, their positioning is "more glued super servers" SuperServers for Grid Computing. The grid system software will give full play to the high-performance computing system and large-capacity data information processing system of each grid node, so that it is a high-performance infrastructure on the network, providing unity of industry users. Manage, easy remote use, secure high performance computing, and large-capacity data processing environments.
Grid provides two ways: web environment and general way. Web mode facing industrial production applications, providing secure grid web services, including resource browsing and batch job management capabilities. Regular ways to develop, providing secure Telnet and FTP applications.
At present, the national high-performance computing environment project is very broad. Many of our industries, such as energy, transportation, meteorology, water conservancy, agriculture, forestry, education, environmental protection, etc., and many departments, units and enterprises involving scientific research, development, education, the demand for high-performance computing grids and information grids is very Huge, especially in the following three aspects.
In terms of land resources: In the past few decades, my country's various land resources departments include the Department of Land and Resources, Water Resources, Forestry Department, Nuclear Industry, Minine Department, Surveying Bureau, Meteorological Bureau, Ocean Bureau and other departments It takes a lot of financial resources to collect resource data for all kinds of underground, ground, and atmospheric, but the valuable wealth and assets of these countries are currently dispersed in many places due to zero-cutting, and the utilization is very low. Organize these data on the grid for national research and use.
In terms of high performance calculations: The five national high-performance computing centers supported by the Ministry of Science and Technology have been run for two years. They unanimously propose urgently need to upgrade computing devices. The establishment of computing grid is conducive to these centers to share resources, play a greater role in the fields such as basic and application basic scientific research, automotive manufacturing, large hydropower projects, oil exploration, meteorological climate, aviation, transportation, financial, medical and health, etc.
In terms of biological information: the informationization and globalization of biological science have become a general trend, and my country's life science community has a strong voice. Some biological research institutions for the leading colleges in Beijing have joined the relevant international organizations, and the modern biological information resources are shared on the grid to improve work efficiency. At present, the application of grid computing establishment of the supporting research of the Biological Information Center is listed as the first task of the "Fifteen Program" Natural Science Foundation.
Advanced computing infrastructure project
Another item: Advanced Computational Infrastructure, also known as the ACICed Computational Infrastructure, which is an infrastructure informatics in the United States. The meaning of ACI is to connect resources distributed in different geographic locations, valuables, databases such as high-speed networks, so that these resources look like a single image of virtual machine, users share resources through ACI, establish Virtual laboratory, discussions and cooperate to carry out research projects. Obviously, the construction of ACI will fundamentally change the structure and concepts used by the computer (especially supercomputers). In my country, the ACI project can use high-performance computers to make it easy to share resources on the Internet, establish a virtual laboratory to promote interdisciplinary and cross-regional joint tasks. In recent years, my country ACI's research has achieved phased outcomes: "Advanced Calculation Infrastructure Beijing Pilot Project (referred to as the" Tsinghua ACI System ') "in the Tsinghua University Computer Department (referred to as the' Tsinghua ACI System ')" has passed the famous computer academician in June 2001 The Identification Committee of the Experts and Acceptance Committee of the Identification Committee. In Tsinghua ACI system, the high-performance computer "THNPSC-2" developed by Tsinghua University "THNPSC-2" has been connected to six application nodes of "self-improvement 2000" in Shanghai University, which can constitute cross-regional and interdisciplinary "virtual experiments" "Research environment.
Tsinghua ACI system is a set of sound resource management systems, task management systems, user management systems and security services and monitoring systems. Many function libraries, application libraries, tools, etc. are saved in the Tsinghua ACI system, which allows users to raise their research levels. For example, a university has domestic leading research results in a certain area, including algorithms and procedures, which can be stored in the Dark Aci system. In the case of authorization, other universities do not have to start from the beginning of similar research, but can enter Tsinghua ACI application library, find and obtain existing research results and experience, conduct research on higher levels and starting points Work, thereby avoiding many repetitive work and speeding up research. At present, Tsinghua ACI system has formed a test environment that supports long-distance joint research.
As the modern technology system is increasingly complex, disciplines and industry urgently need interdisciplinary and cross-regional cooperation and alliances, which is the most important basis for my country's grid calculation development. National High Performance Computing Environment and Tsinghua ACI system in the Chinese Academy of Sciences, two projects have created conditions and environments in "Great Cooperation" and "General Assembly War".
