How do you think about to share any more software development
experiences for the application of the command "getconf _NPROCESSORS_ONLN"
together with make tools?

I am also not able to fully understand what you want and that's why I think Paul wanted an example of what you're trying to do.

We're not even understanding what general issue you are interested in?

Make is multiprocess and parallel and uses all the available processors already - with a high enough -j N setting which is given at the commandline.

So what we can't understand is: what are you trying to do in the recipe?   I imagine doing this on Linux:

make -j $(grep "processor" /proc/cpuinfo  | wc -l)

This ensures that make uses all your processors.

I assume that you want something different from this but you need to explain better, sorry :-)

Regards,

Tim
