Generating Traces of Application Behavior Using Generative Adversarial Networks Público

Abstract

Generally, applications, benchmarks and proxy applications are used for performance analysis of high-performance computing systems. These system performance analysis methods can be challenging or difficult to use, and often application traces are used as workload substitutes. But collecting these traces can also be difficult or time consuming. Therefore, we study synthetic trace generation to synthesize application trace that are indistinguishable from real traces. We propose a machine learning based synthetic data generation method that utilizes temporal graph generative adversarial networks (TG-GANs). We consider communication traces as temporal directed graphs with edge attributes and adjust TG-GAN to generate synthetic data. We use real traces as inputs and generate synthetic ones in some selected representative time windows and evaluate the quality of synthetic data using both quantitative metrics and visualizations. Visualization and quantitative results show that TG-GAN has the potential to generate high-quality synthetic traces but also has some limitations.
