Use interrupt   to interrupt the workers. If test-jl is compute bound, unless the workers are interrupted, they will not exit upon the master process exiting.  nalimilan nalimilan commented on Apr 25, 2014  I can't think of a situation where you'd like the workers started using julia -p N to outlive the master process. Can't the workers be interrupted unconditionally on exit?  amitmurthy The Julia Language member amitmurthy commented on Apr 25, 2014  That's probably the right thing to do.  ViralBShah The Julia Language member ViralBShah commented on Apr 25, 2014  Yes, I agree this is the right thing to do.  StefanKarpinski The Julia Language member StefanKarpinski commented on Apr 26, 2014  In general, unless the user explicitly  detaches  a process somehow, I don't think it makes any sense for a worker to outlive the master. When a process is detached, is it still a worker or something else?
