| 摘要: |
| 基于Lustre 文件系统,对并行文件系统的性能评估和性能建模进行了研究.通过对性能因子的调研,进行了一系列性能评估实验,并提出性能相关性模型(PRModel).在实验评估和PRModel 分析中发现,在不同的性能因子之间存在着紧密的性能相关性.为了挖掘并利用这种相关性信息,提出了一种相对性能预测模型(RPPModel)来预测不同性能因子条件下的性能.为了验证RPPModel 的有效性,设计了大量实验用例.结果表明,预测结果的平均相对误差能够控制在17%~28%的范围内,易于使用且具有较好的预测准确度. |

| Abstract: |
| In this paper, the performance evaluation and modeling of parallel file system based on Lustre file system is studied. After performing a survey on performance factors, a series of performance evaluations via experimental approaches and propose a performance relational model (PRModel). In the experimental and PRModel analysis, it is found that different performance factors have closed performance correlations. In order to mime the relational information, a novel relative performance predictive model (RPPModel) is proposed. This model can be used to predict the overhead over different performance factors. The model is validated through a series of experiments over a variety of performance factors. The experimental results show that the average relative errors results can be controlled within 17%~28%. This model is easy to use and can obtain better prediction accuracy. |
