36 Dell HPC System for Manufacturing—System Architecture and Application Performance
Figure 29 CD-adapco STAR-CCM+ Performance—Explicit BB (4)
Figure 30 through Figure 33 present the same performance data but plotted relative to the “32-cores (1
Node)” result or “64-cores (2 Nodes)” result for problems that require two servers to run. This makes it
easy to see the scaling of the solution—the performance improvement when more cores are used for the
analysis. Problem scalability depends on the cell count and physics of each problem. For many of the
problems, scaling is nearly linear, with relative performance values near eight with 256 cores or eight
nodes.
