Study on Computing Grid Distributed Middleware and Its Application

Focused on the problems that the development of grid application is difficult and the type of discovered resources is restricted when directly using globus toolkit API, some technologies such as grid container, grid plug-in, grid object pool, grid resource adapter and the subgrid communication protocol for computing grid are introduced, the kernel methods and hiberarchy of computing grid distributed middleware (CGDM) are discussed in this paper. By applying these technologies, the computing grid distributed middleware is realized, which is independent of computing grid portal and grid application. The real application in a campus computing grid development shows that this middleware can make it easy to discover new types of grid resources and lead to a quick grid application developing and interconnection between the subgrids.
