为提高调度的效率和资源利用率,提出了一种集成对等(P2P)模式的3层网格资源管理体系结构,将资源的属性以资源组的形式构建层次式的资源管理目录树,提高了资源发现效率.针对网格资源调度中负载均衡和调度最优化等问题,设计了分层次的网格调度策略,并在此基础上提出了一种集成P2P模式的网格资源调度算法.通过集成的方式将资源的网络带宽、计算能力、资源利用率和网络通信开销等属性按照优先权值的大小进行排序,实现网格任务与资源的最佳匹配,仿真实验结果证明了体系结构的可靠性和算法的有效性.
In order to improve scheduling efficiency and resource utilization, a three-tier grid resource management architecture based on peer-to-peer (P2P) model is proposed. The attributes of resources are constructed as hierarchical resource management tree by resource group, Aiming at the problem of load balancing and scheduling optimization in grid resource scheduling, a hierarchical grid scheduling strategy is designed and based on which a grid resource scheduling algorithm with integrated P2P mode is proposed. By using The integrated approach sorts attributes such as network bandwidth, computing power, resource utilization and network communication overhead according to priority values to achieve the best match between grid tasks and resources. The simulation results show that the architecture is reliable The effectiveness of sex and algorithm.
