WebCritical Section Problem. Consider system of nprocesses {p 0, p 1, … p n-1} Each process has . critical section . segment of code. Process may be changing common variables, updating table, writing file, etc. When one process in critical section, no other may be in its critical section. Critical section problem . is to design protocol to solve ...
WebHowever, in Peterson solution, A deadlock can never happen because the process which first sets the turn variable will enter in the critical section for sure. Therefore, if a … WebCritical Section Problem Consider system of n processes {p 0, p 1, … p n-1} Each process has critical section segment of code Process may be changing common variables, updating table, writing file, etc When one process in critical section, no other may be in its critical section Critical section problem is to design protocol to solve this
