Overview

This course delves into the core concepts of C++ concurrency. It covers synchronization mechanisms, including atomic operations and mutexes. Students will learn about the C++ Memory Model, inter-thread communication using condition variables, lock-free programming with atomic variables, and how to avoid common concurrency issues like deadlocks and race conditions.
