Mastering C++ Multithreading

Master multithreading and concurrent processing with C++

About This Book

• Delve into the fundamentals of multithreading and concurrency and find out how to implement them
• Explore atomic operations to optimize code performance
• Apply concurrency to both distributed computing and GPGPU processing

Who This Book Is For

This book is for intermediate C++ developers who wish to extend their knowledge of multithreading and concurrent processing. You should have basic experience with multithreading and be comfortable using C++ development toolchains on the command line.

What You Will Learn

• Deep dive into the details of the how various operating systems currently implement multithreading
• Choose the best multithreading APIs when designing a new application
• Explore the use of mutexes, spin-locks, and other synchronization concepts and see how to safely pass data between threads
• Understand the level of API support provided by various C++ toolchains
• Resolve common issues in multithreaded code and recognize common pitfalls using tools such as Memcheck, CacheGrind, DRD, Helgrind, and more
• Discover the nature of atomic operations and understand how they can be useful in optimizing code
• Implement a multithreaded application in a distributed computing environment
• Design a C++-based GPGPU application that employs multithreading

In Detail

Multithreaded applications execute multiple threads in a single processor environment, allowing developers achieve concurrency. This book will teach you the finer points of multithreading and concurrency concepts and how to apply them efficiently in C++.
Divided into three modules, we start with a brief introduction to the fundamentals of multithreading and concurrency concepts. We then take an in-depth look at how these concepts work at the hardware-level as well as how both operating systems and frameworks use these low-level functions.
In the next module, you will learn about the native multithreading and concurrency support available in C++ since the 2011 revision, synchronization and communication between threads, debugging concurrent C++ applications, and the best programming practices in C++.
In the final module, you will learn about atomic operations before moving on to apply concurrency to distributed and GPGPU-based processing. The comprehensive coverage of essential multithreading concepts means you will be able to efficiently apply multithreading concepts while coding in C++.

Style and approach

This book is filled with examples that will help you become a master at writing robust concurrent and parallel applications in C++.
