Chapter 5, CPU Scheduling

Chapter 5, CPU Scheduling. 5.1 Basic Concepts. The goal of multi-programming is to maximize the utilization of the CPU as a system resource by having a process running on it at all times Supporting multi-programming means encoding the ability in the O/S to switch between currently running jobs

Lecture Topics: 11/15

Lecture Topics: 11/15. CPU scheduling: Scheduling goals and algorithms. Review: Process State. A process can be in one of several states (new, ready, running, waiting, terminated). The OS keeps track of process state by maintaining a queue of PCBs for each state.

Q1. These algorithms require the total CPU bursts of each process. Estimating the CPU bursts is the main difficulty. OSes try to estimate the CPU bursts using exponential smoothing: ? n+1 = ? t n +(1- ? ) ? n where ? (0,1) is the constant weighting factor
