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>

What is cloud computing?

Cloud computing is a computational model for the distribution of services based on a set of resources, such as virtual processing, mass memory, and networking, which can be dynamically aggregated and activated as platforms to run applications, satisfying appropriate levels of service and optimizing the efficiency of resource use.

This can be acquired and released quickly with minimum management effort or interaction with the service provider. This cloud model is composed of five essential characteristics, three service models, and four deployment models.

In particular, the five essential characteristics are as follows:

  • Free and on-demand access: This allows users to access—through user friendly interfaces—the services offered by the provider without human interaction.
  • Ubiquitous access to the network: Resources are available...
