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>

Distributed Python

This chapter will introduce some important Python modules for distributed computing. In particular, we will describe the socket module, which allows you to implement simple applications distributed through the client-server model.

Then, we will introduce the Celery module, which is a powerful Python framework that is used to manage distributed tasks. Finally, we will describe the Pyro4 module, which allows you to call methods that are used in different processes, potentially on a different machine.

In this chapter, we will cover the following recipes:

  • Introducing distributed computing
  • Using the Python socket module
  • Distributed task management with Celery
  • Remote Method Invocation (RMI) with Pyro4
