摘　　要：为提升云计算系统的进程管理效率与负载均衡性,提出一种云计算环境下的双通道数据动态调度模型。分析双通道数据动态调度问题,组建数据空间组织并放置空间索引,获得双通道数据的特性,把整体数据调度任务分化成若干种子任务,计算调度任务量,通过调度流程内任务量极大值,得到调度代价函数与估计函数,得到双通道数据调度内的子任务量,构建层次细节模型动态调整双通道数据与云计算系统的帧率,避免调度模型因帧率不平衡而产生的延迟与停顿的状况,实现动态调度模型的构建。仿真结果证明,所提模型有着调度精准度高与平均吞吐率高的优点。In order to improve the process management efficiency and load balance of cloud computing system,a dual channel data dynamic scheduling model in cloud computing environment is proposed.This paper analyzed the dynamic scheduling problem of dual channel data,constructed the data space organization and places the spatial index,obtained the characteristics of dual channel data,divided the overall data scheduling task into several sub tasks,calculated the scheduling task quantity,obtained the scheduling cost function and estimation function through the maximum task quantity in the scheduling process,obtained the sub task quantity in the dual channel data scheduling,and constructed the hierarchy.A model with level detail was built up to dynamically adjust the frame rate of the dual channel data and cloud computing system,avoid the delay and pause caused by the unbalanced frame rate of the scheduling model,and realize the construction of the dynamic scheduling model.Simulation results show that the proposed model has the advantages of high scheduling accuracy and high average throughput.
