We consider a 201-threaded process with multiple phases. Whenever a thread finishes a phase, it will call checkpoint(). If fewer than half of all the threads are in sleep it will be put into sleep as well, otherwise, it will wake up all of the sleeping thread and they will together proceed to the next phase. Implement checkpoint() with help of mutex and condition variable, the pseudo syntax of which is defined here:
mutex m; cond c;
mutex_init(m, NULL);
cond_init(c, NULL);
mutex_lock(m);
mutex_unlock(m); cond_wait(c, m); cond_signal(c); cond_broadcast(c);
Use the following code framework. mutex m; cond c; mutex. init(m, NULL); cond. init(c, NULL); * Put any additional variables and/or their initial values below * /* It is called whenever a thread finishes a phase */ void checkpoint () {
