Understanding the Linux KernelBy Daniel P. Bovet & Marco CesatiOctober 20000-596-00002-2, Order Number: 0022704 pages, $ Chapter 10 Process SchedulingLike any time-sharing system, Linux achieves the magical effect of an apparentsimultaneous execution of multiple processes by switching from one process to another ina very short time frame. Process switch itself was discussed in Chapter 3, Processes; thischapter deals with scheduling, which is concerned with when to switch and whichprocess to chapter consists of three parts. The section "Scheduling Policy" introduces thechoices made by Linux to schedule processes in the abstract. The section "TheScheduling Algorithm" discusses the data structures used to implement scheduling andthe corresponding algorithm. Finally, the section "System Calls Related to Scheduling"describes the system calls that affect process PolicyThe scheduling algorithm of traditional Unix operating systems must fulfill severalconflicting objectives: fast process response time, good throughput for background jobs,avoidance of process starvation, reconciliation of the needs of low- and high-priorityprocesses, and so on.
