What are the advanced concurrency models in C++14?

C++14 introduced several advanced concurrency features, including improved support for multithreading and the addition of new standard library components like std::shared_mutex and std::scoped_lock.

Can you explain how std::shared_mutex works?

Sure! std::shared_mutex allows multiple threads to read shared data simultaneously while ensuring exclusive access for writing. This improves performance in read-heavy scenarios.

What is the difference between std::mutex and std::shared_mutex?

std::mutex provides exclusive ownership, meaning only one thread can lock it at a time. In contrast, std::shared_mutex allows multiple readers or one writer, enhancing concurrency.

Are there any best practices for using these concurrency models?

Yes, it's best to minimize lock contention, use lock-free data structures when possible, and always ensure that locks are released in a timely manner to avoid deadlocks.
