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 () {

Write a program called assignment3 (saved in a ļ¬le assignment3.java) that computes the greatest common divisor of two given integers. one of the oldest numerical algorithms was described by the greek mathematician, euclid, in 300 b.c. it is a simple but very eāµective algorithm that computes the greatest common divisor of two given integers. for instance, given integers 24 and 18, the greatest common divisor is 6, because 6 is the largest integer that divides evenly into both 24 and 18. we will denote the greatest common divisor of x and y as gcd(x, y). the algorithm is based on the clever idea that the gcd(x, y) = gcd(x ! y, y) if x > = y and gcd(x, y) = gcd(x, y ! x) if x < y. the algorithm consists of a series of steps (loop iterations) where the ālargerā integer is replaced by the diāµerence of the larger and smaller integer. this continues until the two values are equal. that is then the gcd.
