In recent years, along with the Internet popularization and the wide band technology development has brought a broader space for the distributional high performance computation development. Grid computing also rapidly develops. Now, the grid has crossed the initial prototype research phase, and is entering the practical applicat ion. All the signs indicate that the grid will be the future development trend of the network, and it will be technology development.Apart from that, due to meet people' s demand of low-cost computing technology in high-performance scientific computing, high-speed parallel computing has been widely applied. But its deficiencies largely limited its development. The main discussion is how to integrate the two for common development and achieves it.To solve the above problem, the paper firstly discussed the related concept of grid computing and the main idea of Open Grid Services Architecture (OGSA)。 Open Gr id Services Architecture (OGSA) is the latest of a grid architecture. It is a service-centered "service structure", and mainly discusses the grid system architecture highlight from the perspective of users. OGSA adopted the WSDL and SOAP standards of Web services. The systems, which follow OGSA standards, can be in a piece. Users can easily integrate and share of system functions.And through discussions the related displays, architecture andprogramming model of 61 obus Took it 3, it made up of a grid environment. Grid env i ronment by GI obus Too I k i t 3 can not on I y ach i eve the bas i c search and information transmission, but also further up the congregation and decision of information and high levels of tactical information, for example interference and anti-interference, raids and counter-raids, control and anti-control etc. That is difficult to achieve through para Mel env i ronment.Next, through the research of para I lei computing, the paper analyzes the problem, which wi 11 be face in para I la computing in grid environment, and gives the project. These problem include major appi i cat ion strategy, the division and distribution of tasks, communication mode > concurrent programming and security problem.Moreover, the paper gives the main code of the implement of paral lei computing in the grid-computing environment. And it gives the result by N queens' example and carries on the performance analysis to this system.Finally, this article summarizes the work inadequate, given the outlook for further work.
