Concurrency with Modern C++

Concurrency with Modern C++

By: Rainer Grimm

Overview of this book

C++11 is the first C++ standard that deals with concurrency. The story goes on with C++17 and will continue with C++20/23. Concurrency with Modern C++ is a practical guide that gets you to grips with concurrent programming in Modern C++. Starting with the C++ memory model and using many ready-to-run code examples, the book covers everything you need to improve your C++ multithreading skills. You'll gain insight into different design patterns. You'll also uncover the general consideration you have to keep in mind while designing a concurrent data structure. The final chapter in the book talks extensively about the common pitfalls of concurrent programming and ways to overcome these hurdles. By the end of the book, you'll have the skills to build your own concurrent programs and enhance your knowledge base.

Data-Parallel Vector Library

The data-parallel vector library provides data-parallel (SIMD) programming via vector types. SIMD stands for Single Instruction Multiple Data and means that one operation is performed on many data in parallel. Each modern processor architecture provides SIMD extensions, but there exists no standardised C++ interface to use them. The following table gives an overview of various SIMD extensions.

SIMD Extensions
Architecture SIMD Extension Register Width
ARM 32 / 64 NEON 128 bit
Power / PowerPC AltiVec 128 bit
  VSX 128 bit
x86 / AMD 64 MMX / 3DNow 64 bit
  SSE 128 bit
  AVX / AVX2 / AVX-512 128 bit / 256 bit / 512 bit

For example, the SSE extension allows it to add four 32 bit ints in parallel. The effect is that it is...
