基于虚拟组织的网格资源管理和分配

Grid resource management and allocation based on virtual organization

讨论了网格计算环境下基于虚拟组织的资源管理机制与理论模型。在基于虚拟组织的网格资源管理系统中引入信誉度模型,实现资源的分类管理,改进了Buyya等提出基于代理的费用—时间最优调度算法中没有考虑任务迁移时间的不足。仿真结果表明,该资源管理系统能够根据用户的Deadline,Budget以及信誉度要求合理分配资源,实现效用驱动的资源管理和分配。

This paper discusses the resource management mechanisms and theoretical models in the virtual organization （VO）-based grid computing environment. The model of credibility was introduced in the resource management system of Grid based on virtual organizations and the category management of resources was achieved. Buyya＇s broker-based cost-time optimization scheduling algorithm which did not consider the transmission time of task was improved. The simulation results show that the resource management system can assign resources reasonably according to the deadline, budget and requirements of credibility of user and achieve utility-driven resource management and assignment.
