What are the alternatives to atomic operations in concurrent programming?
There are several alternatives to atomic operations, such as locks, semaphores, and message passing. Each has its own use cases.
Can you explain how locks work as an alternative?
Locks allow only one thread to access a resource at a time, preventing race conditions. They can be simple or more complex like read-write locks.
What are the downsides of using locks?
Locks can lead to issues like deadlocks and reduced performance due to contention among threads. It's important to use them judiciously.
Are there any lock-free alternatives?
Yes, lock-free data structures and algorithms, like compare-and-swap, can be used to avoid the pitfalls of locks while ensuring thread safety.
