The default minimum number of threads is 1, set this to your max threads if you already know that it will run the fastest with that configuration. In some cases simulations start with a few objects but more are added later. By setting it to a low value initially the simulation will run as more objects are added chrono parallel will automatically increase the number of threads. If min threads is > max threads, weird stuff might happen!
The default maximum threads is equal to the number visible via openMP.
Only perform thread tuning if max threads is greater than min_threads; I don't really check to see if max_threads is > than min_threads not sure if that is a huge issue.
Member Data Documentation
◆ min_threads
| int chrono::settings_container::min_threads |
The minimum number of threads that will ever be used by this simulation.
If you know a good number of threads for your simulation set the minimum so that the simulation is running optimally from the start.
◆ perform_thread_tuning
| bool chrono::settings_container::perform_thread_tuning |
System level settings.
If set to true chrono parallel will automatically check to see if increasing the number of threads will improve performance. If performance is improved it changes the number of threads, if not, it decreases the number of threads back to the original value.
◆ step_size
| real chrono::settings_container::step_size |
The timestep of the simulation.
This value is copied from chrono currently, setting it has no effect.
