Mastering C++ Multithreading

By: Maya Posch

Overview of this book

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++.

Atomic Operations - Working with the Hardware

Multithreading Implementation on the Processor and OS

The foundation of any multithreaded application is formed by the implementation of the required features by the hardware of the processor, as well as by the way these features are translated into an API for use by applications by the operating system. An understanding of this foundation is crucial for developing an intuitive understanding of how to best implement a multithreaded application.

This chapter looks at how hardware and operating systems have evolved over the years to arrive at the current implementations and APIs as they are in use today. It shows how the example code of the previous chapter ultimately translates into commands to the processor and related hardware.

Topics covered in this chapter include the following:

  • The evolution of processor hardware in order to support multithreading concepts
  • How operating systems...
