Abstract: In this paper, a reputation-based Grid scheduling model is proposed to counter the inherent unreliability of computing resources in Grid overlays. The proposed approach creates a scalable networking of Grid sites for supporting dependable scheduling. The scheduling model considers reliability of a Grid resource as a statistical property, which is globally computed in the Grid overlay based on dynamic feedbacks. The proposed model can dynamically adapt to changing resource conditions and offer significant performance compared to traditional approaches in the event of unsuccessful job execution or resource failure. We evaluate and demonstrate the feasibility of the approach through an extensive trace driven simulation. The results show that this scheduling model can reduce the makespan up to 30% and successfully isolate the failure- prone resources from the system.
