TAILIEUCHUNG - Lecture Operating systems: Internals and design principles (6/E): Chapter 5 - William Stallings

Chapter 5 - Concurrency: Mutual exclusion and synchronization. After studying this chapter, you should be able to: Discuss basic concepts related to concurrency, such as race conditions, OS concerns, and mutual exclusion requirements; understand hardware approaches to supporting mutual exclusion; define and explain semaphores; define and explain monitors;. | Chapter 5 Concurrency: Mutual Exclusion and Synchronization Operating Systems: Internals and Design Principles, 6/E William Stallings Dave Bremer Otago Polytechnic, . ©2008, Prentice Hall These slides are intended to help a teacher develop a presentation. This PowerPoint covers the entire chapter and includes too many slides for a single delivery. Professors are encouraged to adapt this presentation in ways which are best suited for their students and environment. 1 Roadmap Principals of Concurrency Mutual Exclusion: Hardware Support Semaphores Monitors Message Passing Readers/Writers Problem 2 Multiple Processes Central to the design of modern Operating Systems is managing multiple processes Multiprogramming Multiprocessing Distributed Processing Big Issue is Concurrency Managing the interaction of all of these processes The central themes of operating system design are all concerned with the management of processes and threads: • Multiprogramming: The management of multiple .
