Show how you would fix the problem { make additions/alterations as needed to the code.
Consider the following implementation of a reusable barrier. When put in use, N processes will be executing the barrier code in a loop - expecting to rendezvous at some point after the first line, and before entering the critical section. For (global) initial values: # rendezvous count0 mutex - Semaphore (1) turnstile1Semaphore (O) turnstile2Semaphore (O) mutex.wait( count +1 if countN: turnstile1.signal) mutex.signal) turnstile1.wait(O turnstile1.signal) # critical sectio mutex.wait() count-= 1 if count0: mutex.signal () turnstile2.wait(O turnstile2.signal ) turnstile2.signal) Consider the following implementation of a reusable barrier.
