CFD-Based HPCMP Systems Assessment Using AERO, AVUS, and OVERFLOW-2

Each year the High Performance Computing Modernization Program (HPCMP) obtains new supercomputing hardware through a rigorous acquisition process known as technology insertion (TI). TI is based primarily on application benchmarks. Its suite of applications spans many disciplines and is carefully constructed to ensure that it accurately reflects the HPCMP workload. For the most recent TI, (TI-05), the application codes AERO, AVUS, and OVERFLOW 2 were used to represent the computational fluid dynamics (CFD) portion of the workload. This paper will compare the performance of the major HPCMP architectures in executing each of the following CFD application test cases found within the TI-05 benchmarking suite: AERO standard, AVUS standard/large, and OVERFLOW 2 standard/large.
