Please find my past solution here: How to program multicore[^].

Again, don't interfere in thread/process affinity unless you know exactly what are you doing!

Now that's a bold statement! :) 5!

Thank you, Niklas. It's better to understand that affinity can make more harm than benefit. I can see very few applications where it can be useful. One of them is supporting of some "bad" hardware which lack interrupt-driven operation and needs stupid permanent polling.
