Parallel file system measurement and modeling using colored petri nets
Quang Hai Nguyen, Amy Apon · 2012
Parallel file systems are significant challenges for high performance data-intensive system designers due to their complexity. Being able to study features and designs before building the actual system is an advantage that a simulation model can offer. This paper presents a detailed simulation-based performance model of the PVFS parallel file system. The model is developed using Colored Petri Nets. The goal of the simulation model is to provide a tool to examine end-to-end performance of a parallel file system and to build a foundation that can be easily expanded upon in the future to model many different types of parallel file systems. The performance evaluation results of the model demonstrate that the model performance behavior is close to the expected behavior of the real PVFS file system.
