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 compute server configured with dual 16-core Intel Xeon Gold 6346 processors. Larger values indicate better overall performance. These results show the performance advantage available with 3rd generation Intel Xeon Scalable processors. The 24-core Intel Xeon Gold 6342 provides very good performance for these benchmarks. The 32-core Intel Xeon Gold 6338 and Platinum 8358 processors provide on average 7% and 14% better performance respectively than the Gold 6342.
Figure 4 presents the parallel scalability of the Simcenter STAR-CCM+ benchmark models using up to six computational servers configured with Intel Xeon Platinum 8358 processors. The performance is presented relative to the performance of a single node (64 cores total).
The parallel scalability for most of these benchmark models is good, with the system demonstrating nearly linear parallel scaling. Some of the smaller models do not scale as well as the larger benchmark cases, but this is to be expected as communication overhead limits the parallel scalability of smaller cases.
