Two quick additional things: * If you feel adventurous and want to benchmark on the GPU, to see which GPU does what, here’s something that you can benchmark: https://github.com/projectchrono/DEM-Engine or perhaps the FSI solver, which comes into play in CRM terramechanics sims as well. * If you end up looking at the OpenMP scaling and/or GPU aspects, please share the results on the forum so that everybody learns something out of your effort. In that case, it would be great to also share a link to the code that you used to benchmark. Thank you, Dan --------------------------------------------- Bernard A. and Frances M.

An analysis on how efficiently the load is balanced across the threads for different demos would certainly be helpful!
