The scale and complexity of highly distributed data intensive systems is approaching a point where traditional performance evaluation techniques are becoming difficult to apply. Specifically, use of traditional stochastic performance evaluation methods encounters difficulties in (1) complexity (i.e., scale of the models and intractability of corresponding solution techniques) and (2) parameter estimation (i.e., needed by the models).In this project we seek to address these two challenges through the use of machine learning techniques. Such techniques have not been traditionally employed in this area, but have emerged recently as a possible direction. We envision that this will lead us not only to better machine learning approaches but will also facilitate merging of machine learning-based techniques with more traditional approaches to performance evaluation, where we anticipate obtaining better results than can be obtained through either approach alone.The broader impacts of this work will be to enable a deeper understanding of the role, advantages, and limitations of machine learning approaches in performance evaluation of large-scale systems as well as their relationship with more traditional approaches. Broader impact also includes improved interdisciplinary education at the graduate and undergraduate levels and diversity efforts.

高度分布式数据密集型系统的规模和复杂性正接近传统性能评估技术变得难以应用的程度。 具体来说，使用传统的随机性能评估方法会遇到以下困难：（1）复杂性（即模型的规模和相应解决技术的难处理性）和（2）参数估计（即模型所需的）。在这个项目中，我们寻求通过使用机器学习技术来解决这两个挑战。 此类技术传统上并未在该领域使用，但最近作为一个可能的方向出现。 我们预计，这不仅将引导我们找到更好的机器学习方法，还将促进基于机器学习的技术与更传统的绩效评估方法的融合，我们预计将获得比单独通过任何一种方法获得更好的结果。这项工作的影响将是使人们能够更深入地了解机器学习方法在大规模系统性能评估中的作用、优势和局限性，以及它们与更传统方法的关系。 更广泛的影响还包括改善研究生和本科生的跨学科教育以及多元化努力。
