Concurrency with Modern C++

By: Rainer Grimm

Overview of this book

C++11 is the first C++ standard that deals with concurrency. The story goes on with C++17 and will continue with C++20/23. Concurrency with Modern C++ is a practical guide that gets you to grips with concurrent programming in Modern C++. Starting with the C++ memory model and using many ready-to-run code examples, the book covers everything you need to improve your C++ multithreading skills. You'll gain insight into different design patterns. You'll also uncover the general consideration you have to keep in mind while designing a concurrent data structure. The final chapter in the book talks extensively about the common pitfalls of concurrent programming and ways to overcome these hurdles. By the end of the book, you'll have the skills to build your own concurrent programs and enhance your knowledge base.

The Future: C++23

Concurrency in C++20
Concurrency in C++20

It is difficult to make predictions, especially about the future (Niels Bohr).

Executors

An executor consists of a set of rules about where, when and how to run a callable unit. They are the basic building block to execute and specify if callables should run on an arbitrary thread, a thread pool, or even single threaded without concurrency. The extended futures, the extensions for networking N4734 depend on them but also the parallel algorithms of the STL, and the new concurrency features in C++20/23 such as latches and barriers, coroutines, transactional memory, and task blocks eventually use them.

Extended futures

Tasks called promises and futures, introduced in C++11, have a lot to offer, but they also have a drawback: tasks are not composable into powerful workflows. That limitation does not hold for the extended futures in C++20/23. Therefore, an extended future becomes ready, when its predecessor (then) becomes ready...
