C++11/14/17 Atomics the Deep dive: the gory details, before the story consumes you!

Log in to save this to your schedule and see who's attending!

In 2011, C++11 atomics offered three memory models but 6 settings. Most compilers have started implementing most of these (relaxed, seq_cst, acquire, release, acq_rel) but not consume (For that you will need to see Paul's talk which naturally follows this talk.) For this, I will deep dive into what each memory model setting means (especially for Games Development and low latency, a new SG14 in the C++ Standard) and how C++11 atomics are used to improve handling of mutable shared state. We have improved on it in C++14 and have more crazy things planned for C++17. I will also look at how C++ atomics are a natural precursor to SG5's Transactional Memory which was approved in Lenexa for publication.
