14 Dell EMC Ready Bundle for HPC Digital Manufacturing—Siemens’ Simcenter STAR-CCM+™ Performance | January 31, 2018
The benchmarks models, LeMans_100M_Coupled and LeMans_514M_Coupled, require two or more servers
for sufficient memory capacity (for simplicity we assumed linear speedup for the node counts fewer than the
number required to hold the model). The results for these cases start with the first valid result obtained for
each benchmark problem. The smallest three models display almost linear speedup to 256-way, and the
largest model (LeMans_514M_Coupled) displays super-linear speedup from 6-node to 8-node.
Overall, STAR-CCM+ displays excellent single node performance and parallel scalability up to 8 nodes on the
Dell EMC Ready Bundle for HPC Digital Manufacturing with the EBB building blocks.
