What are some common challenges in lock-free design?

What are some common challenges in lock-free design?

Lock-free design can be challenging due to issues like memory management, ensuring progress, and handling contention.

Can you explain how memory management works in lock-free designs?

In lock-free designs, memory management often involves techniques like hazard pointers or epoch-based reclamation to prevent memory leaks.

What are the benefits of using lock-free data structures?

Lock-free data structures can improve performance by reducing contention and avoiding deadlocks, making them suitable for high-concurrency scenarios.

Are there any specific algorithms that are commonly used in lock-free designs?

Yes, common algorithms include compare-and-swap (CAS), load-link/store-conditional (LL/SC), and various forms of queues and stacks.
