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++.

Summary

In this chapter, we looked at how to integrate GPGPU processing into a C++ application in the form of OpenCL. We also looked at the GPU memory hierarchy and how this impacts performance, especially in terms of host-device communication.

You should now be familiar with GPGPU implementations and concepts, along with how to create an OpenCL application, and how to compile and run it. How to avoid common mistakes should also be known.

As this is the final chapter of this book, it is hoped that all major questions have been answered, and that the preceding chapters, along with this one, have been informative and helpful in some fashion.

Moving on from this book, the reader may be interested in pursuing any of the topics covered in more detail, for which many resources are available both online and offline. The topic of multithreading and related areas is very large and touches...
