Modeling and performance evaluation of QoS-aware job scheduling of computational grids
摘要
Abstract
To achieve high quality of service (QoS) on computational grids,the QoS-aware job scheduling is investigated for a hierarchical decentralized grid architecture that consists of multilevel schedulers.An integrated QoS-aware job dispatching policy is proposed,which correlates priorities of incoming jobs used for job selecting at the local scheduler of the grid node with the job dispatching policies at the global scheduler for computational grids.The stochastic high-level Petri net (SHLPN) model of a two-level hierarchy computational grid architecture is presented,and a model refinement is made to reduce the complexity of the model solution.A performance analysis technique based on the SHLPN is proposed to investigate the QoS-aware job scheduling policy.Numerical results show that the QoS-aware job dispatching policy outperforms the QoS-unaware job dispatching policy in balancing the high-priority jobs,and thus enables priority-based QoS.关键词
