Does increasing the number of CPU cores contribute to faster simulation performance in this case?

CUDA solver is faster than CPU in nearly all scenarios.
You see a greater benefit of GPU with larger numbers of particles (1 million +) however I still use GPU for smaller numbers of particles (e.g. 1000- 10,000) as its still faster than CPU, just the difference in speed is not as great. I'm not sure where the CPU benefit over GPU cross-over is, if the simulation is a few hundred particles I would run on CPU.

Hi Nathen,
CPU's don't really influence the simulation speed if running on GPU. Typically we recommend using 4 CPU's with a GPU however all the computational effort is spent on the GPU.
