Based On The Ogsa Grid Computing Resource Management And Scheduling

Grid Computing is the third wave of information technology after Internet andWeb technology. It will change the mode of sharing distributed resources and servicesfinally. The Open Grid Service Architecture (OGSA) is current version of the Gridarchitecture. Based on the mechanism of Web Service, OGSA advanced an idea ofGrid Services, whose interfaces address discovery, dynamic service creation, lifetimemanagement, notification and registry.The study of Grid technology in this thesis is based on an important project ingeophysical research institute of ShengLi Petroleum —《The Application andResearch of Grid Technique in Seismic Data Processing and Interpretation》.Based onOGSA and GT3 (Globus Toolkit 3), this research proposed a settlement scheme of anapplication system about the management of computing grid resources.At first the thesis briefly introduced the definition of the grid and the realizationtechnique of the grid service in the grid computing. Then, contrasted the differentarchitectural structures on grid and analyzed the application value of OGSA. Wedepicted design and implementation of the system in detail, and then certificated theproblem of the service call from different platform.Based on cluster software and Grid Middleware, first, the system works as anagent to connect them to work together. Then, utilizing the service date of the GridService, the system completes the management of computational resource and realizesthe unified management of resource, users and tasks. Last, the system also solves safecertification problem and so on.This system offers high capability computing condition in Internet. Anycomputer can access the computer resource service anytime. The research has beenconfirmed by the geophysical research institute of ShengLi Petroleum .Finally, summarized the deficiency of our work, and pointed out the perspectiveof Grid Computing.
