Question
(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.
