Sorry for not having answered more quickly, I don't check the forum every day
Bill2's Process Manager have been created when multi processors start to reach personnal computers, may be in 2006-2007.
At this time, having more than 4 cores was only seen in big servers with multi processors.
I've made the affinity system to handle 32 cores (or 16 cores with 16 HT), because it was like a limit for 32bits systems at this time.
Even if BPM works on Windows Server, it has never been designed to handle such big hardware.
And since 2007, Windows multitasking has been strongly improved, and I don't think BPM is really useful now.
And, as you can have seen, BPM is not currently in dev anymore.
So, I'm sorry, but I can't answer positively to your request.
Thanks for still using BPM, from Russia!
