A CPU scheduling algorithm simulator

This paper presents a simulator that uses graphical animation to convey the concepts of various scheduling algorithms for a single CPU. The simulator is unique in a number of respects. First, it uses a more realistic process model that can be configured easily by the user. Second, it graphically depicts each process in terms of what the process is currently doing against time. Using this representation, it becomes much easier to understand what is going on inside the system and why a different set of processes is a candidate for the allocation of the CPU at different time. A third unique feature of the simulator is that it allows the user to test and increase his understanding of the concepts studied by making his own scheduling decisions, through the very easy-to-use graphical user interface of the simulator. The simulator can be used by students in operating system courses or by anyone interested in learning CPU scheduling algorithms in an easier and a more effective way.
