Concurrency and Mutual Exclusion

This lecture covers the importance of concurrency and parallelism, the need for atomic operations, and the implementation of locks for mutual exclusion in critical sections. It discusses the issues with threads, the use of interruptible locks, spin locks, and hardware-supported mechanisms like Test-and-Set and Compare-and-Swap. The lecture emphasizes the significance of ensuring atomicity through mutual exclusion to prevent data races and achieve correct program execution.
