Schedulingis important in many different computer environments. One of the most important areas is scheduling which programs will work on the CPU. This task is handled by the Operating System (OS) of the computer and there are many different ways in which we can choose to configure programs. ...
Developing CPU scheduling algorithms in operating system and understanding effect of various algorithms in practice can be difficult and deadly because of the requirement to update the operating system and test operating system kernel code and quantity the succeeding presentation of operating system on a...

For situations 1 and 4, there is no choice in terms of scheduling. A new process (if one exists in the ready queue) must be selected for execution. There is a choice, however, for situations 2 and 3. When scheduling takes place only under circumstances 1 and 4, we say that the sche...

Multilevel Queue Scheduling - like RR, except have multiple queues. Typically, classify processes into separate categories and give a queue to each category. So, might have system, interactive and batch processes, with the priorities in that order. Could also allocate a percentage of the CPU to...
Jobs in the System queue are scheduled FCFS, those in the Interactive queue are scheduled using non-preemptive SJF while those in the Batch queue are scheduled using SRTF. A fixed preemptive priority scheduling is implemented between queues, i.e., System jobs have the highest priority, ...
This paper describes a concept-specific simulator designed for teaching CPU scheduling in operating system courses. The simulator takes the execution information of a set of processes as input. It outputs a report showing the wait time, termination time, turnaround time of each process, the system...
