Shouldn't be. 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.
Good to know. Does anyone have a solution for make across multiple
machines, perhaps using ssh?
