Abstract
Concerning the low scheduling ratio caused by complicated QoS process and precise match in resource scheduling of grid,in this paper,the authors classified QoS parameters as according to their characteristic,defined QoS parameters distance and estimated QoS parameters similarity.A QoS managing model was presented,and a maximum matching scheduling algorithm was described based on the model.Finally simulations were performed to compare the performance of the maximum matching scheduling algorithm with that of the multiple QoS-based resource scheduling algorithm.The experiments show that the maximum matching scheduling algorithm is efficient on system throughput and task fulfilling ratio and resource utilization ratio within grid computing environments.
