Yes, exactly.
I can not use the parameter "-j" directly for the start of the main
make process in my case so far.
based on some processing of the recipe.
One of the variables (or make rules) will call the command
"getconf _NPROCESSORS_ONLN".
The corresponding processes should be efficiently started for
parallel background execution after a serial data preparation
was finished.
This makes very little sense. In a properly written Makefile, your
serial preparation step will remain serial no matter what "-j" arguments
are used, so it should be safe to just invoke "make -j xx" at the
beginning and let things run serially or in parallel as necessary.
