Coordination and Scheduling

This lecture covers the concepts of coordination and scheduling in operating systems. It starts by discussing the challenges of sequence coordination, lost wakeup problems, and different scheduling algorithms. The lecture then delves into the implementation of coordination primitives like sleep and wakeup, as well as the issues with spinlock solutions. It explores the use of condition variables and semaphores to address the lost wakeup problem. Additionally, the lecture explains the role of the scheduler in selecting threads to run, emphasizing the importance of response time and fairness in scheduling decisions.
