基于BACKFILL的并行计算作业调度算法研究.pdf
在众多的并行作业调度算法中,Backfill通常被广泛认为是有效提高CPU利
用率的一种算法,该算法是在FCFS算法的基础上,将队列中较小的作业回填
(backfill)到空闲CPU,以提高CPU利用率。但是,当空闲CPU数量仍然无
法满足Backfill算法中小作业的回填要求时,系统仍有部分CPU闲置,因而也难
以达到更好的提高CPU利用率的目的。
为了改进Backfill算法不能充分利用空闲CPU这一不足之处,本文提出了基
于Backfill算法的需求自适应改进算法;而对于共享内存体系结构的并行计算机
系统,本文还提出了基于Backfill算法的资源自动回收改进算法。
在Backfill的基础上,需求自适应改进算法利用CPU的空闲空间作为判断依
据,扩展了可参与填充操作作业的数量。该算法通过合理修改队列中作业的参数一一所需CPU数量和估计运行时间,以满足Backfill算法下无法利用的CPU空闲,弥补了Backfill算法的不足,大大提高了并行计算机系统的CPU资源的利用率。
资源自动回收改进算法以正在运行的作业的CPU利用率为依据,通过动态调
整正在运行的作业的CPU数,扩大可供回填(backfill)的CPU空间,使得Backfill算法无法回填(backfill)的作业得到运行,弥补了Backfill算法的不足,也很好的提高了共享内存体系结构并行计算机系统的CPU利用率。
两种改进算法都是在Backfill的基础上,从不同的技术层面来改进Backfill
算法,通过与FCFS、Backfill相结合,共同参与并行计算机系统的作业调度,实现CPU资源利用率的不断提高。
