Cover Story: OpenFOAM is a CFD software widely used in both industry and academia. For the assessment of the software components and the code profiling during the exaFOAM project, lightweight but significant benchmarks should be used. The answer was to develop microbenchmarks covering a broad band of applications, including incompressible and compressible flow, combustion, viscoelastic flow and adjoint optimisation. The performances using HPC systems with Intel and AMD processors (x86_64 architecture) and Arm processors (aarch64 architecture) have been benchmarked. For the workloads in this study, the mean performance with the AMD CPU is 62% higher than with Arm and 42% higher than with Intel. The AMD processor seems particularly suited, resulting in an overall shorter time-to-solution. View this paper
