用于虚拟计算中心的交互式作业调度策略

An interactive jobs schedule strategy in virtualized compute centers

描述了一个用于虚拟计算中心,旨在加强为交互式作业及时分配资源的调度算法,该算法基于抢占式作业调度策略,能快速将资源分配给交互式作业,且能使资源被抢占的作业很容易重新恢复运行。通过模拟计算中心运行环境测试,实验结果表明:这个调度算法不仅对交互式作业的资源及时分配有显著的改善,提高了资源利用率,而且还大大缩短了批处理作业的响应时间。

The paper describes a scheduling algorithm for the virtual computing center,which is aimed at strengthening the timely allocation of resources for the interactive tasks.The algorithm is based on preemptive scheduling strategy and can quickly allocate resources to interactive tasks,and enable tasks whose resources have been preempted easily to resume running.Through computing center testing to run simulated environment,test results show that： the scheduling algorithm have improved not only timely allocation of resources interactive operations significantly,and improved resource utilization,but also greatly shortened the response time of a batch job.
