【摘要】：针对云计算环境下用户所需资源与服务资源规格不完全相符以及在资源预留过程中完整资源被切割而产生的资源碎片问题,提出一种云环境下考虑碎片资源重利用的动态资源管理策略。研究了云计算环境下资源碎片的形成原因,构建了碎片资源池,制定了任务对碎片资源接收的度量标准,在充分考虑当前任务对资源查找、调度、匹配的同时,进一步讨论了任务调度对资源的分割情况,进而指出资源碎片对后续任务接收能力的影响,搭建了云计算环境下动态资源碎片调度模型。理论分析和Cloudsim仿真实验证明,该资源管理策略能有效实现碎片资源的优化重组,提高了资源对后续任务的接收能力,与此同时保证了较高的资源利用率。
[Abstract]:In view of the problem that the resource requirements of users in cloud computing environment are not completely consistent with the specification of service resources and that the complete resources are cut in the process of resource reservation,A dynamic resource management strategy considering the reuse of debris resources in cloud environment is proposed.In this paper, the causes of resource fragmentation in cloud computing environment are studied, and the debris resource pool is constructed, and the metrics of task to debris resource receiving are established. While fully considering the current task to find, schedule and match resources,Furthermore, the paper discusses the partition of resource by task scheduling, and then points out the influence of resource fragmentation on the receiving ability of subsequent tasks, and builds a dynamic resource debris scheduling model in cloud computing environment.Theoretical analysis and Cloudsim simulation experiments show that the proposed resource management strategy can effectively realize the optimization and reorganization of debris resources, improve the ability of receiving resources for subsequent tasks, and at the same time, ensure a high resource utilization rate.
