A solution to the critical-section problem must satisfy the following three requirements: Mutual Exclusion, Progress, and Bounded Waiting. (1) Describe the Mutual Exclusion (5 marks) and (2) prove that Peterson's solution satisfies the Mutual Exclusion requirement (5 marks): do { Process i flag[i]= true; turn = j; while (flag[j] && turn == j) { ; // busy, wait } critical section flag [i] = false; remainder section } while (true); do { Process j flag[j] = true; turn = i; while (flag[i] && turn ==1) { ; // busy, wait critical section flag[j] = false; remainder section } while (true); A solution to the critical-section problem must satisfy the following three requirements: Mutual Exclusion, Progress, and Bounded Waiting.
