CppCon 2024

This talk will highlight the key discussions in ISO C++ parallelism and concurrency related proposals since the last CppCon discussed in the Kona 2023, Tokyo 2024, and St. Louis 2024 C++ standard meetings. We aim to update CppCon attendees every year in this area. We focus on features that are close to standardization, and/or appear to be relatively non-controversial so that you get a look ahead on what is coming for the next C++ release.

This talk, by the Concurrency TS2 Editors will describe all the features and show how they can be used as well as give their motivation, background and how they fit within the overall framework of C++ parallelism and concurrency.

1. Atomic
2. Hazard pointer extensions
3. Pointer Tagging
4. Parallel Algorithms, Parallel Range algorithms

There are other features being discussed at these meetings, but they are still in development and could still change. So we focus on those features that seem close to approval, interesting, and/or are relatively non-controversial. We will show the use cases of each and describe how some of them are already heading to C++26 or beyond. This will help programmers in concurrency, lock-free programming, low-latency applications how to take advantage of each of these important facilities.
