By Richard Haselgrove (10 Jan 2021):
This may not help after all. Simulation timeline shows tasks running MT for around 15-20 minutes, and replacing one-for-one as cache depletes, as in real life. But at simulation 04:16:00 it switches to single-threaded - not allowed by project preferences. I'll continue with the experiment - I believe there's a problem with MT fetch and idle cores.
