The benchmark problems from the standard Simcenter STAR-CCM+ benchmark suite were evaluated on the reference system. Simcenter STAR-CCM+ benchmark performance is measured using the Average Elapsed Time metric which is the average elapsed time per solver iteration. A smaller elapsed time represents better performance. Figure 3 shows the relative performance for a selection of Simcenter STAR-CCM+ benchmarks on a single server.
The results in Figure 3 are plotted relative to the performance of a single server configured with AMD EPYC 7502 processors. The benchmarks were run using all processor cores available in the server. Larger values indicate better performance. These results show the performance advantage available with 7003 series AMD EPYC processors. The 32-core AMD EPYC 7543 processors provide very good performance for these benchmarks. Per server, the 64-core AMD EPYC 7713 provides a significant performance advantage over the 32-core processors.
Figure 4 presents the parallel scalability when running STAR-CCM+ with up to eight nodes configured with AMD EPYC 7513 processors and ConnectX-6 HDR InfiniBand. All processor cores in each server were used when running these benchmarks. The performance at each node count is presented relative to the performance of a single node.
The parallel scalability for these benchmarks is as expected, with most models scaling nearly linearly to eight nodes. Several of the smaller benchmark cases such as TurboCharger do not scale as well as the other benchmarks, but this is expected due to the model size and physics of these benchmark cases.
