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>

Introducing serverless computing

In recent years, a new service model named Function as a Service (FaaShas been developed, which is also known as serverless computing.

Serverless computing is a cloud computing paradigm that allows the execution of applications without worrying about problems related to the underlying infrastructure. The term serverless could be misleading; in fact, it could be thought that this model does not foresee the use of processing servers. In reality, it indicates that the provisioning, scalability, and management of the servers on which the applications are executed are administered automatically and in a completely transparent manner for the developer. Everything is possible thanks to a new architecture model called serverless.

The first FaaS model dates back to Amazon, when the AWS Lambda service was released in 2014. Over time...
