Python Parallel Programming Cookbook - Second Edition

By: Giancarlo Zaccone

Overview of this book

<p>Nowadays, it has become extremely important for programmers to understand the link between the software and the parallel nature of their hardware so that their programs run efficiently on computer architectures. Applications based on parallel programming are fast, robust, and easily scalable. </p><p> </p><p>This updated edition features cutting-edge techniques for building effective concurrent applications in Python 3.7. The book introduces parallel programming architectures and covers the fundamental recipes for thread-based and process-based parallelism. You'll learn about mutex, semaphores, locks, queues exploiting the threading, and multiprocessing modules, all of which are basic tools to build parallel applications. Recipes on MPI programming will help you to synchronize processes using the fundamental message passing techniques with mpi4py. Furthermore, you'll get to grips with asynchronous programming and how to use the power of the GPU with PyCUDA and PyOpenCL frameworks. Finally, you'll explore how to design distributed computing systems with Celery and architect Python apps on the cloud using PythonAnywhere, Docker, and serverless applications. </p><p> </p><p>By the end of this book, you will be confident in building concurrent and high-performing applications in Python.</p>

Using the Python socket module

A socket is a software object that allows data to be sent and received between remote hosts (via a network) or between local processes, such as Inter-Process Communication (IPC).

Sockets were invented at Berkeley as part of the BSD Unix project. They are based precisely on the management model of input and output of Unix files. In fact, the operations of opening, reading, writing, and closing a socket occur in the same way as the management of Unix files, but with the difference that should be considered are the useful parameters for communication, such as addresses, port numbers, and protocols.

The success and spread of socket technology have gone hand in hand with the development of the internet. In fact, the combination of sockets with the internet has made communication between machines that are of any type, and/or are scattered...
