Previously I’ve learned that RhinoCommon is not thread-safe.
From my own experience, setting up multiple threads in a custom plugin and trying to access RhinoCommon from a few threads at the same time yielded unpredictable results.
What is not clear to me is if RhinoCommon is thread-safe when you run multiple instances of Rhino simultaneously.
I’d like to see about running a few instances of Rhino to run the same operations on a few different files simultaneously. These operations can take many minutes to compute and was thinking I could speed work up by running a few things at the same time. I’d only do this, however, if I know that I will get very consistent results.
