Concurrency with Modern C++

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.

Atomics

Atomics are the base of the C++ memory model. By default, the strong version of the memory model is applied to the atomics; therefore, it makes much sense to understand the features of the strong memory model.

Strong versus Weak Memory Model

As you may already know from the subsection on Contract: The Challenges, with the strong memory model I refer to sequential consistency, and with the weak memory model I refer to relaxed semantic.

Strong Memory Model

Java 5.0 got its current memory model in 2004, C++ in 2011. Before that, Java had an erroneous memory model, and C++ had no memory model. Those who think this is the endpoint of a long process are entirely wrong. The foundations of multithreaded programming are 40 to 50 years old. Leslie Lamport defined the concept of sequential consistency in 1979.

Sequential consistency provides two guarantees:

  • The instructions of a program are executed in the order written down.
  • There is a global order of all operations on all...
