A Failed Attempt: Just Using Loads/Stores
Explore the limitations of building locks using just a single flag with loads and stores in concurrent programming. Learn why this approach fails to ensure mutual exclusion and causes performance problems due to spin-waiting, highlighting the need for more sophisticated lock mechanisms.

To move beyond interrupt-based techniques, we will have to rely on CPU hardware and the instructions it provides us to build a proper lock. Let’s first try to build a simple lock by using a single flag variable. In this failed attempt, you’ll see some of the basic ideas needed to build ...
