Exercise: Parallel Architectures
In the tutorial, all solutions will be presented by students. Please be prepared for all questions as the exercise will focus on discussion, not on understanding the question and gathering the knowledge. Some challenging questions are usually a lot more difficult and require knowledge that was not presented in the lecture.
Implement double-address compare-and-swap with compare-and-swap.
Scalable Reader-Writer Locks
Fair reader-writer locks protect a critical section, such that multiple readers can enter the critical section concurrently, provided no writer is attempting to enter or holding the lock. Thereby at most one writer may be in the critical section at any point in time, provided no readers are in the critical section.
