Consider the following processes:

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 CPU$1.[10$ pts$]$

$($b$)$ FCFS with a Ready Queue per CPU. Processes A$,$ B$,$ and C go to CPU$1$ and

processes D$,$ E$,$ and F go to CPU$2.[10$ pts$]$

$($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 CPU$1.[10$ pts$]$
