摘要
现代计算机系统的性能已经由受限于CPU转变为受限于I/O,因此,并行I/O是缓解这一难题的有效方法。文章通过对集群计算系统中I/O调度策略的研究,提出了一种新的自适应平等划分的I/O调度策略,并将它们与已经存在的调度策略进行比较。实验结果表明了所提出策略的优越性。
The limitation about the performance of modern computer system has been translated to I/O subsystem from CPU. So parallel I/O is an efficient method to solve the problem. A new adaptive equal partition scheduling policy is proposed by researching the I/O scheduling on cluster computing system. Then the comparison between the proposed policy and the existing policies is done and the experimental result shows the superiority of the proposed policy.
