My understanding (which may be wrong) is that make calculates the dependency graph first, not in parallel. Then it executes as many parallel tasks as the -j option asks for, or that make sense... whichever is smaller. Since the dependency graph is a DAG, make should, in theory, be smart enough to see that two dependencies depend on the same node and run only one job to build the depended-upon node. I routinely use "make -j `nproc`" and have never run into any issues. Regards, Dianne.
