Performance Characteristics of an Unstructured CFD Solver on PC-Clusters
Mattias Sillén · 45th AIAA Aerospace Sciences Meeting and Exhibit · 2007
Linux PC-Clusters are a cost-efficient platform for parallel computational fluid dynamics (CFD) applications. This paper investigates the performance characteristics of an unstructured explicit flow solver on multiple clusters. Different node configurations and network architectures are considered in the evaluation. Single processor performance as well as overall parallel performance are compared and evaluated and recommendations are made for performance and cost-efficiency.
