Abstract: A role-based computation resource sharing platform called RB-CRSP was proposed in this paper. The node roles and functions were strongly considered in design toplogy of RB-CRSP. All the nodes in RB-CRSP were assigned as server, coordinator, worker, and client. By using the united programming model, it could be in harness with the immense computational resource available in the Internet for parallel and distributed computation efficiently. RB-CRSP platform was also load balancing and fault-tolerant, which was strongly supported by hardware and credit standing based scheduling algorithm and the workers oriented fault tolerance policy. In order to demonstrate the effectiveness of RB-CRSP, a serial of simulation experiments were done. The results obtained from performance analysis show that RB-CRSP is feasible and efficient which can provide a new way for computing resource sharing over the Internet. The hardware conditions and availability of machines are important factors in this test.
