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.

A remote procedure call with RPyC


Remote Python Call (RPyC) is a Python module that is used for remote procedure calls as well as for distributed computing. The idea at the base of RPC is to provide a mechanism to transfer control from a program (client) to another (server), similar to what happens with the invocation of a subroutine in a centralized program. The advantages of this approach are that it has very simple semantics and knowledge and familiarity of the centralized mechanism of a function call. In a procedure invocation, the client process is suspended until the process server has performed the necessary computations and has given the results of computations. The effectiveness of this method is due to the fact that the client-server communication takes the form of a procedure call instead of invocations to the transport layer so that all the details of the operation of the network are hidden from the application program by placing them in local procedures called stubs. The main...
