I fully agree that the nr of CPUs option urgently needs standardisation. I didn't make my own statistics what values are currently used, but as nobody disagreed I assume that you are right that "Threads" is is most common one. Therefore I will use "Threads" in my engine.
It does not matter if you are currently using another name for an option that does the same thing, just keep it if you think that name is better. But in the interest of the users of your engine, please also support a 'Threads' option.
That is not a good idea. Please replace your option with "Threads".

If the GUI has two options for the same feature, the GUI will show an input box for both. If the user changes only one of the inputs, it is not clear which input will be sent to the engine first. So the engine will use one of the settings and it is undefined which one.
