Python Parallel Programming Cookbook

By: Giancarlo Zaccone

Overview of this book

This book will teach you parallel programming techniques using examples in Python and will help you explore the many ways in which you can write code that allows more than one process to happen at once. Starting with introducing you to the world of parallel computing, it moves on to cover the fundamentals in Python. This is followed by exploring the thread-based parallelism model using the Python threading module by synchronizing threads and using locks, mutex, semaphores queues, GIL, and the thread pool. Next you will be taught about process-based parallelism where you will synchronize processes using message passing along with learning about the performance of MPI Python Modules. You will then go on to learn the asynchronous parallel programming model using the Python asyncio module along with handling exceptions. Moving on, you will discover distributed computing with Python, and learn how to install a broker, use Celery Python Module, and create a worker. You will understand anche Pycsp, the Scoop framework, and disk modules in Python. Further on, you will learnGPU programming withPython using the PyCUDA module along with evaluating performance limitations.

Developing a client-server application with Pyro4

In this recipe, we'll show you how to build a simple client-server application with Pyro4. The application that we'll show here is not complete, but is equipped with all the methods that will successfully complete and improve it.

A client-server application indicates a network architecture in which, generally, a client computer or terminal connects to a server for the use of a certain service, such as the sharing of a certain resource hardware/software with other clients and relying on the underlying protocol architecture. In our system, the server manages an online shopping site, while the clients manage the customers that are registered on this site and connect to it for shopping.

How to do it…

For the sake of simplicity, we have three scripts. The first one represents the object client in which we have customer management, the second script is the object shop, and the third script is the object server.

For the server (, the code...
