@zareen said in CS604 Assignment 3 Solution and Discussion:

Question No 02 12 Marks
Suppose a computer lab comprises of two printers, three scanners, and four ROM writers. There are three programs currently running on some computer. Assume program P1 is currently allocated a printer and two ROM writers and it is waiting for a scanner. Program P2 is allocated a scanner and it is waiting for a printer. Program P3 is allocated two ROM writers, a scanner, and a printer. Draw the corresponding resource allocation graph for these three programs. Also specify if the system is in a deadlocked state or not?

The system is not in deadlock state as it is clear from the above graph it is multi instance and circular weight.

Solution:
Q. 1 Answer
P0 P4 P3 P2 P1 P5 0 2 5 9 10 16 24
Total Waiting Time = 0+2+5+1+10+16 = 34 Seconds
Average Waiting Time = 34/6 = 5.66 Seconds

Q.2 Answer:
Solution 1:
P0 P1 P3 P0 P2 P3 P2 P3 P2 P2 0 8 16 24 31 39 47 55 57 65 66
Turnaround time= Exit Time- Arrival Time

Turnaround time for P0 = 31-0 = 31
P1 = 16-4 = 12
P2 = 66-18 = 48
P3 = 57- 5= 52

Total Turnaround Time = 39+12+48+52 = 143
Average Turnaround Time = 143 / 4 =35.75 millisecond

Waiting Time= Turnaround Time- Burst Time

Waiting time for P0 = 31-15 = 16
P1 = 12-8 = 4
P2 = 48-25 = 23
P3 = 52-18 = 34

Total Waiting Time = 16+4+23+34 =77
Average Waiting Time = 77 / 4 =19.25 millisecond

Solution 2:
P0 P1 P3 P2 P0 P3 P2 P3 P2 P2 0 8 16 24 31 39 47 55 57 65 66
Turnaround time= Exit Time- Arrival Time

Turnaround time for P0 = 39-0 = 39
P1 = 16-4 = 12
P2 = 66-18 = 48
P3 = 57- 5= 52

Total Turnaround Time = 39+12+48+52 = 151
Average Turnaround Time = 151 / 4 =37.75 millisecond

Waiting Time= Turnaround Time- Burst Time

Waiting time for P0 = 39-15 = 24
P1 = 12-8= 4
P2 = 48-25= 23
P3 = 52-18 = 34

Total Waiting Time = 24+0+5+29 = 85
Average Waiting Time = 85 / 4 =21.25 millisecond
