Consider the following proposed solution for the critical section problem. There are n processes: P0…Pn – 1. In the code, function pmax returns an integer not smaller than any of its arguments. For all i, t[i] is initialized to zero.Code for Pi:do { c [i]=1; t[i] = pmax (t [0],…, t[n-1]) +1; c[i]=0; for every j ≠ I in {0,…,n-1} { while (c[j]); while (t[j] != 0 && t[j]<=t[i]) ; ] Critical section; t[i] =0; Remainder Section;} While (true);Which one of the following is TRUE about the above solution? |
A. | At most one process can be in the critical section at any time |
B. | The bounded wait condition is satisfied |
C. | The progress condition is satisfied |
D. | It cannot cause a deadlock |
Answer» B. The bounded wait condition is satisfied | |
