GPE4CGSP: interoperability between heterogeneous grid infrastructures

In this paper we present GPE4CGSP, which targets the interoperability between GPE (Grid Programming Environment) and CGSP (ChinaGrid Support Platform). The web services technique and gridftp data transfer protocol are used to implement the interoperation between GPE and CGSP. Grid application can be deployed to CGSP through GPE. Without modification, GPE client can freely visit and use the resources in CGSP. Typically, end users can submit jobs to CGSP through GPE application client. GPE4CGSP provides one feasible way for the interoperability of heterogeneous grid infrastructures. The evaluation proves that the job execution time of GPE4CGSP is less than that of GPE4GTK.
