Simcenter STAR-CCM+ Performance
14 Dell EMC Ready Solution for HPC Digital Manufacturing—Siemens’ Simcenter STAR-CCM+™ Performance
4 Simcenter STAR-CCM+ Performance
Simcenter STAR-CCM+ is a Computational Fluid Dynamics (CFD) application commonly used across a wide
range of CFD and multi-physics applications. CFD applications typically scale well across multiple processor
cores and servers, have modest memory capacity requirements, and typically perform minimal disk I/O while
in the solver section. However, some simulations, such as large transient analysis, may have greater I/O
demands.
The benchmark problems from the standard STAR-CCM+ benchmark suite were evaluated on the reference
system. 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 4
shows the measured performance for a selection of the STAR-CCM+ benchmarks on a single server.
Figure 4 Single Server Relative Performance—STAR-CCM+ 13.06.012
The results in Figure 4 are plotted relative to the performance of a single CBB server configured with Intel
Xeon Gold 6242 processors. For comparison, the figure also includes performance data for prior generations
of the Ready Solution for HPC Digital Manufacturing. This includes the 14G CBB with Intel Xeon Gold 6142
processors and the 13G CBB with 16-core Intel Xeon E5-2697A v4 processors. Larger values indicate better
overall performance. These results show the performance advantage available with 14G servers with 2
nd
generation Intel Xeon Scalable processors (code name Cascade Lake). The Intel Xeon Gold 6242 and 6248
processors provide very good performance for these benchmarks and the Intel Xeon Gold 6252 provides
about 5% better performance than the Gold 6248.
