I'm not sure what you mean by "task" here. Make has a concept of a
"job", as you can see by searching around the help documentation. I
think each job will be executing one command script for a particular
rule at any given time, and the command script itself is executed
serially. The parallelization comes in when you have multiple jobs, so
multiple command scripts can be executed simultaneously.

I agree that it is a challenge, and a very general problem.
