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>

Types of distributed applications

Distributed applications can be classified according to the degree of distribution:

  • Client-server applications
  • Multi-level applications

Client-server applications

There are only two levels and the operations are carried out entirely on the server. As an example, we can mention the classic static or dynamic websites. The tools for the realization of these types of applications are the network sockets, whose programming is possible in various languages, including C, C ++, Java, and, of course, Python.

The term client-server system refers to a network architecture in which a client computer or client terminal is generally connected to a server for the use of a certain service; for example, the...
