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

Setting up a development environment


Regardless of which platform and GPU you have, the most important part of doing OpenCL development is to obtain the OpenCL runtime for one's GPU from its manufacturer. Here, AMD, Intel, and NVidia all provide an SDK for all mainstream platforms. For NVidia, OpenCL support is included in the CUDA SDK.

Along with the GPU vendor's SDK, one can also find details on their website on which GPUs are supported by this SDK.

Linux

After installing the vendor's GPGPU SDK using the provided instructions, we still need to download the OpenCL headers. Unlike the shared library and runtime file provided by the vendor, these headers are generic and will work with any OpenCL implementation.

For Debian-based distributions, simply execute the following command line:

$ sudo apt-get install opencl-headers

For other distributions, the package may be called the same, or something different. Consult the manual for one's distribution on how to find out the package name.
