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++.

Installing Open MPI


For the remainder of this chapter, we will focus on Open MPI. In order to get a working development environment for Open MPI, one will have to install its headers and library files, along with its supporting tools and binaries.

Linux and BSDs

On Linux and BSD distributions with a package management system, it's quite easy: simply install the Open MPI package and everything should be set up and configured, ready to be used. Consult the manual for one's specific distribution, to see how to search for and install specific packages.

On Debian-based distributions, one would use:

$ sudo apt-get install openmpi-bin openmpi-doc libopenmpi-dev

The preceding command would install the Open MPI binaries, documentation, and development headers. The last two packages can be omitted on compute nodes.

Windows

On Windows things get slightly complex, mostly because of the dominating presence of Visual C++ and the accompanying compiler toolchain. If one wishes to use the same development environment...
