Chapter 9: Unlprocessor Scheduling 9. Consider the following process set example: Process Base Priority 60 30 90 They run in a system that uses multilevel feedback scheduling using round robin within each priority queue. The system makes use of one second pre-emption. The following formulas apply with integer division: CPUCPUi- CPU,(i) Indicate the execution scheduling for the given example for the firstsix seconds by shading the executing process. Include the priority and CPU counts. Assume no processes block themselves and no other processes are ready to run. Chapter 9: Unlprocessor Scheduling 9.
