Performance and Scalability of the CODA CFD Software on the AMD Naples and Rome Architectures

Abstract

Computational Fluid Dynamics (CFD) simulations are playing an increasingly important role in aircraft design. They provide detailed insight into the aerodynamic behavior of components and help reduce costs and development time. CODA is a next-generation CFD software for aerodynamic simulations of fully equipped aircraft. Developed by the German Aerospace Center (DLR), the French Aerospace Laboratory (ONERA) and Airbus, the CODA CFD software is one of the key applications represented in the European Center of Excellence for Engineering Applications (Excellerat). This work evaluates the performance of the CODA CFD software on the two large HPC production systems at DLR based on the AMD Naples and Rome architectures with the NASA Common Research Model. The evaluation includes a comparison of compute performance, an assessment of strong and weak scaling behavior on the largest available partitions of the two production systems, and a discussion of performance and scalability using various performance analysis tools.
