Research And Application On University Computing Grid Middleware

The computing grid technology is rapidly developing in domestic and foreign, and is of a huge impetus function for the computing resources sharing. This paper takes building ChengDu University of Technology (CDUT) University Computing Grid (UCGrid) as a goal. First, based on the current computing grid technology and the success case research, design the CDUT University Computing Grid framework. Second, in order to achieve the goal of the fast design and develops a concrete university computing grid platform, design and develop a middleware of university computing grid. Finally develop the CDUT UCGrid Application Platform on the middleware of UCGrid.In this paper, the key research object is the middleware of UCGrid which has encapsulated UCGrid operations and built a bridge between the UCGrid application and Globus Toolkit. In the UCGrid middleware design process, the UCGrid object, the UCGrid object pool, the UCGrid plug-in and so on has be proposed and implemented. The UCGrid object, the UCGrid object pool uses in the data management, enables the data the operation to have the same pattern, simultaneously create the different UCGrid object and pool found the different data field so that the UCGrid data has the localization independence. The UCGrid plug-in is the engine of the UCGrid operation. Separately realizes the different UCGrid plug-in according to the certain function piecemeal. The result is not only that make each plug-in function to be independent, but also that the UCGrid plug-in "insert and pull" characteristic enhances the ability to increase and expand UCGrid function. Moreover, as the aspect in the university grid middleware security authentication system as well as the resources organization, "computing grid community" theory has carried on the preliminary exploration and the realization.
