摘　　要：针对虚拟集群内部关联性和并行作业的运行特点,基于虚拟集群在线迁移机制,提出一种虚拟化资源整合算法.先对系统建模,描述云计算环境下的虚拟化资源整合问题;再使用区域划分法对异构资源分类,从而初步降低问题的规模和求解难度;最后提出在同构子域中进行虚拟集群迁移的FFD_grp算法.采用同种负载和多种资源分配方法模拟多种资源使用情况,并对该方法进行验证.实验结果表明,FFD_grp算法能显著提高资源整合效果,有利于抑制资源碎片的产生.In view of the internal correlation of virtual cluster and the running feature of parallel jobs,we proposed a virtual resource consolidation algorithm based on virtual cluster live migration.Firstly,we modeled the system and described the virtual resource consolidation problem in cloud computing environment.Secondly,we used region division to classify heterogeneous resources so as to reduce the size and complexity of the problem.Finally,we proposed a FFD_grp algorithm for virtual cluster migration in the homogeneous subdomains.We used the same load and various resource allocation methods to simulate a wide variety of resource usage,and then vertified FFD_grp algorithm.The experimental results show that it can significantly improve the effect of resource consolidation and restrain the occurrence of resource fragment.
