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.

General Considerations

Implementing thread-safe data structures is special. Before I dive into each of these special concerns, here is a concise overview including the answers you have to give.

  • Locking Strategy: Should the data structure support coarse-grained or fine-grained locking? Coarse-grained locking might be easier to implement but introduces contention.
  • The Granularity of the Interface: The bigger the interface of the thread-safe data structure, the more difficult becomes it to reason about the concurrent usage of the data structure.
  • Typical Usage Pattern: When readers use your data structure mainly, you should not optimise for writers.
  • Avoidance of Loopholes: Don’t pass internals of your data structure to clients.
  • Contention: Do concurrent client requests seldom or often use your data structure?
  • Scalability: How is the performance characteristic of your data structure when the number of concurrent clients increases or the data structure is bounded...
