NPTEL : Introduction to Operating System

Question

Your friend wants to design synchronization primitives and tells you that he would be better off by strictly ensuring that the processes alternate the critical section. Your response would be:

1.  That might not satisfy the “progress” requirement

2.  That might not satisfy the “mutual exclusion” requirement

100.  That might not satisfy the “bounded wait” requirement

500. I guess that would suffice.

Answer 1

From the question's reference i think that friend is using "Strict alteration"  technique.

In this technique we are using turn variable. That variable can be used one process at a time 

So in this method progress is not achieved.

So I think answer is option (a).
