The value-added services hosted by GSEE are wrapped into grid services. GSEE and other nodes with spare processing capability are organized into virtual organization (VO). A task scheduling algorithm is proposed to overcome the performance bottleneck problem when system gets overload by leveraging existing resources in the same VO. GSEE is modeled by Stochastic Petri Net (SPN) in this paper. And simulation experiment is done based on this model, with the help of SPNP (stochastic Petri net package) to test the performance of GSEE. The simulation result verifies GSEE can really improve system performance.enText/Conference Paper1617-5468
