Overview of this book

C++ is a highly portable language and can be used to write both large-scale applications and performance-critical code. It has evolved over the last few years to become a modern and expressive language. This book will guide you through optimizing the performance of your C++ apps by allowing them to run faster and consume fewer resources on the device they're running on without compromising the readability of your code base. The book begins by helping you measure and identify bottlenecks in a C++ code base. It then moves on by teaching you how to use modern C++ constructs and techniques. You'll see how this affects the way you write code. Next, you'll see the importance of data structure optimization and memory management, and how it can be used efficiently with respect to CPU caches. After that, you'll see how STL algorithm and composable Range V3 should be used to both achieve faster execution and more readable code, followed by how to use STL containers and how to write your own specialized iterators. Moving on, you’ll get hands-on experience in making use of modern C++ metaprogramming and reflection to reduce boilerplate code as well as in working with proxy objects to perform optimizations under the hood. After that, you’ll learn concurrent programming and understand lock-free data structures. The book ends with an overview of parallel algorithms using STL execution policies, Boost Compute, and OpenCL to utilize both the CPU and the GPU.

Concurrency

In this chapter, we are going to explore how to write concurrent programs in C++ using threads with shared memory. We will look at ways to make concurrent programs correct by writing programs that are free from data races and deadlocks. This chapter will also contain some pieces of advice on how to make concurrent programs run with low latency and high throughput.

Before we go any further, it should be said that this chapter is not a complete introduction to concurrent programming, nor will it cover all the details of concurrency in C++. Instead, this chapter is an introduction to the core building blocks of writing concurrent programs in C++, mixed with some performance-related guidelines. If you haven't been writing concurrent programs before, it is probably wise to go through some introduction texts to cover the theoretical aspects of concurrent programming...
