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++.

Proper multithreading


In the preceding chapters, we have seen a variety of potential issues which can occur when writing multithreaded code. These range from the obvious ones, such as two threads not being able to write to the same location at the same time, to the more subtle, such as incorrect usage of a mutex.

There are also many issues with elements which aren't directly part of multithreaded code, yet which can nevertheless cause seemingly random crashes and other frustrating issues. One example of this is static initialization of variables. In the following sections, we'll be looking at all of these issues and many more, as well as ways to prevent ever having to deal with them.

As with many things in life, they are interesting experiences, but you generally do not care to repeat them.
