CS604 Operating Systems Assignment 2 Solution & Discussion Fall 2019

Question No 01           4+3+3=10 marks

Assume you have to apply Shortest Job First (SJF) scheduling algorithms on the set of different processes given in the table below. The CPU burst time is also given for each process. Consider that all the processes arrive in the ready queue within time 0 seconds except P2 that arrive in ready queue within time 8 seconds. You are required to show the Gantt Chart to illustrate the execution sequence of these processes and calculate the Total Waiting Time and Average Waiting Time for the given processes by using SJF algorithm.

Process CPU Burst Time (seconds)    P0 2    P1 6    P2 1    P3 4    P4 3    P5 8

Question No 02            4+3+3=10 marks

Consider a scenario where you have to apply Round Robin scheduling algorithm on the below given set of processes with each having a quantum size=8 milliseconds. The CPU burst time and arrival time for each process is also provided in the given table. You are required to show the Gantt Chart to illustrate the execution sequence of these processes. Moreover, calculate the Average Turnaround Time and Average Waiting Time for given processes by using round robin algorithm.
Process CPU Burst Time (Milliseconds) Arrival Time(Milliseconds)    P0 15 0    P1 8 4    P2 25 18    P3 18 5
