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>

Python Debugging and Testing

This last chapter will introduce two important software engineering topics—debugging and testing—that are important steps in the software development process. 

The first part of the chapter is focused on code debugging. A bug is a mistake in a program and can cause different problems that may be more or less serious depending on the situation. To encourage programmers to search for bugs, special software tools are used, called debuggers; using these software tools, we have the ability to find errors or malfunctions within a program by taking advantage of specific debugging functions, an activity that exists precisely for identifying the portion of software affected by a bug.

In the second part, the main topic is software testing:  it is a process used to identify deficiencies of correctness, completeness...
