Abstract

What is a memory model and why does C++ need it so badly? I’ll try to explain both the practical and the theoretical side of things. We’ll look into a few simple multithreaded idioms, sketch the Java memory model, and show the differences between Java and C++. For the theoretically minded, I’ll do my best to explain sequential consistency and the “happens before” relationship necessary to describe data races. We’ll look into the C++ atomic library.
