Question
Consider the following processes:
Process Arrival Time Service Time
A 0 4
B 1 3
C 2 3
D 2 2
E 3 1
F 5 3


Show (draw the schedule, x-axis is time, and one row for each CPU) how the above
processes execute over time on a system with 2 CPUs. Compute the average turnaround
time for all processes and the average utilization for each CPU under each of the following
schedulers:
(a) FCFS with a single Ready Queue. A process gets scheduled once one of the CPUs
is available. When both CPUs are available, we select CPU1. 
(b) FCFS with a Ready Queue per CPU. Processes A, B, and C go to CPU1 and processes
D, E, and F go to CPU2. 
(c) HRRN with a single Ready Queue. A process gets scheduled once one of the CPUs
is available. When both CPUs are available, we select CPU1.
