  • 简介:数据存取延期成为了高端计算系统的突出的性能瓶颈。在系统设计减少数据存取延期的关键是减少数据货摊时间。存储器地区和并发是影响现代存储器系统的性能的二个必要因素。因为全面存储器系统性能上的存储器并发的影响很好没被理解,然而,存在在利用数据存取并发上在很少减少数据货摊时间学习焦点。在这研究,一双新奇数据货摊时间模型,为地区和并发的联合努力的L-C模型和为数据上的纯失误的效果的下午模型阻止时间,被介绍。模型提供数据存取延期的新理解并且为表演优化提供新方向。基于这些新模型,先进缓存优化的一张概括表格被介绍。当时,被数据并发贡献了,把38个条目仅仅,21个条目由数据地区作出贡献,它显示出数据并发的值。在这研究介绍的L-C和下午模型和他们的联系结果和机会为数据中央的建筑学和算法现代计算系统设计的未来重要、必要。
