pmk is a utility for building projects using multiple processors
In a project with a valid Makefile, run python3 parse.py to generate build.pmk. You only need to generate this once (unless you change your makefile/build files). After that, simply run pmk for a single processor or mpirun -np 4 pmk (change 4 to however many processors you want).
$ cd test_long
# generate test files
$ sh gen.sh
# generate build.pmk
$ python3 ../parse.py
# run pmk with 4 processors
$ mpirun -np 4 ../pmk
