Abstract: In order to aggregate and utilize network resource efficiently and conveniently, a .NET based approach for general computing resource sharing environments over the Internet called GCRSE was proposed. Using the node function role approach, GCRSE was composed of three kinds of node: role peers, named server, volunteers and clients. With the Web services of .NET, GCRSE can submit, execute and transport the tasks and subtasks about the parallel applications across the Internet. Besides the master-slave style parallel programming model and the divide-conquer style were also supported on GCRSE. A heartbeat message and subtask oriented fault tolerance policy were also used which can achieve the reliability. The results obtained from performance analysis show that the throughput and speedup of GCRSE are good and it is a feasible and efficient approach which can provide a new way for computing resource sharing over the Internet.
