摘要
针对传统调度方法执行效率普遍偏低的问题,提出了一种基于截止期感知(DA)的云计算数据中心虚拟机(VM)调度方法:基于处理时间将VM分配给需要调度的工作流,进而基于截止期完成工作的调度。通过设计模拟计算环境对提出的方法及基于资源分组的调度方法进行对比分析,实验结果表明,提出的算法可以有效降低平均等待时间和延迟,提高云计算调度的运行效率。
A workflow virtual machine（VM）scheduling method based on deadline aware is proposed to settle the low efficiency problem of traditional scheduling method.VM was allocated to the jobs based on processing time,workflow scheduling was completed based on deadline aware.A simulation environment was established to compare the proposed method with resource grouping method.Results show that the proposed method can reduce the average waiting time and violation effectively,and enhance the operating efficiency of workflow scheduling.
