The Application And Study Of Chemgrid Based On Globus And CGSP

With the development of science and technology and the popularity of Internet, demands for computers by people increase dramatically. They are no longer satisfied with the general information sharing, but to hope to share almost all the resources. The emergence of grid makes the dream come ture. It can realize resources sharing and coordinated working in the virtual network environments, and finally eliminate the information islands and resource islands. There are more and more researches and applications on grid with the development of grid technology. As the third network techniques, at present, people pay more attention to the grid, considering it to be a very important prospect of scientific research and application. Many organizations try their best to put more attention to grid and integrate their characteristics with the technology, in order to display a distinctive charm of grid.The thesis first talks about the basic theory of Grid and our application projects. After demonstrating examples of services about chemical applications based on Globus and CGSP(ChinaGrid Support Platform), it then does a meticulous study on the differences between GT4(Globus Toolkit 4) and CGSP, in regard to many ways such as architecture, design method, creating steps, security, prospects in chemical application and so on. And the modification and improvement of CGSP user's interface are discussed in details and a new interface type is added in CGSP.Based on the comparison and analysis of the middleware, the thesis proposes a new model about ChemGrid(chemical grid) which is suitable for chemical field and a integration of certain requires and grid characteristics. The modle based on Globus and using benefits of CGSP for reference designs core architecture and expanded architecture for chemical application. And it supplies portal to put release function up, in order to make the resouses more transparent for users, that built a bridge between the ChemGrid application and Globus Toolkit. It's easier for users to make use of complicated grid resourse, and will play an important role of hi quality computing application in chemical teaching and research works.
