STAR-CCM+™ Performance
4 Simcenter STAR-CCM+ Performance
Simcenter STAR-CCM+ is a multiphysics application used to simulate a wide range of products and designs
under a wide range of conditions. The benchmarks reported here mainly use the computational fluid dynamics
(CFD) and heat transfer features of STAR-CCM+. 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 may have greater I/O demands, such as transient
analysis.
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—Simcenter STAR-CCM+
The results in Figure 4 are plotted relative to the performance of a single server configured with AMD EPYC
7601 processors. The benchmarks were run using all processor cores available in the server. Larger values
indicate better overall performance. These results show the performance advantage available with 7002
series AMD EPYC processors. The 32-core AMD EPYC 7452 and 7502 processors provide good
performance for these benchmarks. Per server, the 64-core AMD EPYC 7702 provides a significant
performance advantage over the 32-core processors.
