    How does using a lock lose the benefit of parallelism? If all of your threads are waiting for something to happen before proceeding (great use for a barrier, BTW), there's no parallelism to be lost because they're all idle anyway. Commented Jun 3, 2019 at 2:31

    @Blrfl a single lock makes a serial section and they all need to pass it one by one as far as i understand. i don't mind using a lock, i'm basically asking if there's a lock that doesn't induce serialization, that multiple threads can pass in parallel. Commented Jun 6, 2019 at 20:08
