Enable/Disable OMP or change thread count

[Onyx Bennett]

Hello, I am looking at Chrono for one of my CS courses and I was curious if there is a way to run demos with different thread counts or if any of them have OMP that I could play with. I haven't had success searching for these on my own.

Or if there are any demos that take input my group and I can scale, that would be extremely helpful

Hello,

Yes, look at the member function of ChSystem SetNumThreads.

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

Thank you so much!

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
