An efficient Web services based approach to computing grid

The main focus of grid is the resource sharing at substrate level. With present existing tool kits, however, great efforts still need to be made to implement resource sharing at higher level, such as publishing grid services on grid substrates. In this paper, we present construction platform for specific computing grid (CPSCG), a system that renders the ease and speediness for users to construct a computing grid. Shared computational resources are wrapped to Web services and exported as grid services with little human labor in CPSCG. Web user interface, which is automatically built by system based on Web services, is supplied to end users for them to invoke grid services
