仿真是一种快速、可控和可再现的方法，用于在各种条件下评估分布式计算平台的新算法。然而，模拟的真实性很少得到评估，这严重质疑了整个研究结果的适用性。在本文中，我们提出了我们的努力，从应用程序的痕迹，建立平台模型，允许跨分布式基础设施的文件传输的准确模拟。文件传输是性能的关键，因为文件传输时间的可变性对应用程序的性能有重要影响。我们提出了一种方法来建立现实的平台模型，从应用程序的痕迹，并提供了定量评估的准确性派生的模拟。结果表明，所提出的模型能够正确地捕捉现实生活中的变化，并显着优于国家的最先进的模型。
Simulation is a fast, controlled, and reproducible way to evaluate new algorithms for distributed computing platforms in a variety of conditions. However, the realism of simulations is rarely assessed, which critically questions the applicability of a whole range of findings. In this paper, we present our efforts to build platform models from application traces, to allow for the accurate simulation of file transfers across a distributed infrastructure. File transfers are key to performance, as the variability of file transfer times has important consequences on the dataflow of the application. We present a methodology to build realistic platform models from application traces and provide a quantitative evaluation of the accuracy of the derived simulations. Results show that the proposed models are able to correctly capture real-life variability and significantly outperform the state-of-the-art model.
