To get a more accurate evaluation of scheduling algorithms, we can use simulations. Running simulations involves programming a model of the computer system.
Software data structures represent the major components of the system. The simulator has a variable representing a clock.
As this variable’s value is increased, the simulator modifies the system state to reflect the activities of the devices, the processes, and the scheduler.
As the simulation executes, statistics that indicate algorithm performance are gathered and printed.
