Figure 5 STAR-CCM+ Parallel Scaling—Intel Xeon Gold 6252
Figure 5 presents the parallel scalability of the STAR-CCM+ benchmark models using up to eight CBB nodes
configured with Intel Xeon Gold 6252 processors. The performance is presented relative to the performance
of a single node (48 cores total), except for the LeMans_100M and vtmBenchmark_178M cases, where
performance is presented relative to the performance of two nodes.
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.
