| 摘 要： | 随着处理器速度和网络传输速度的快速提升，I／O成为限制计算机性能的一大瓶颈，并行I／O提供了解决这一问题的有效途径。在并行I／O的实现中，数据访问调度策略对系统的性能有着重要的影响。文章通过对集群计算中现有I／O数据访问调度策略的研究，针对调度器瓶颈问题，提出了自主协助动态I／O调度策略，实验结果表明了所提出策略的有效性。

| Abstract: | With the rapid growth of processor and network transfer speeds,I/O has become a bottleneck limiting computer system's performance,while parallel I/O provides an effective way to solve this problem.In realizing parallel I/O,I/O scheduling policy plays a very important role in system's high performance.By analyzing existing I/O scheduling algorithms on cluster computing system,a new strategy named the dynamic I/O scheduling algorithm of autonomic assistance is put forward,aiming at scheduler bottleneck.Experimental results demonstrate the efficiency of proposed policy. |
