This technical report details the ongoing HPC Benchmark Project, which aims to establish a framework for consistent performance comparisons using OpenFOAM technology across various hardware platforms and configurations. The report outlines the project's objectives, including the evaluation of Time to Solution (TtS), computational efficiency, and Energy to Solution (EtS), the latter being increasingly significant in the context of exascale computing. It describes the creation of a shared code repository that provides user guides and scripts for running datasets on different HPC architectures, ensuring a standardized reference for performance comparison. The report also includes a list of test cases, such as the 3-D Lid Driven Cavity flow and HPC motorbike, which are designed to stress-test linear algebra solvers and evaluate performance across different hardware configurations. Additionally, it discusses the setup of linear algebra solvers and presents hardware comparison results, highlighting the importance of maintaining a fixed computational load for benchmarking purposes.
