What are memory ordering models and how do they relate to race conditions?

Memory ordering models define the rules for how operations are seen by different threads. They help prevent race conditions.

Can you explain what a race condition is?

A race condition occurs when two or more threads access shared data and try to change it at the same time, leading to unpredictable results.

How do different memory ordering models affect race conditions?

Different models, like sequential consistency or relaxed consistency, dictate how operations are ordered, impacting the likelihood of race conditions.

What are some common strategies to avoid race conditions?

Common strategies include using locks, semaphores, or atomic operations to ensure that only one thread can access shared data at a time.
