Overview of this book

IPython is an interactive computational environment in which you can combine code execution, rich text, mathematics, plots, and rich media. This book will get IPython developers up to date with the latest advancements in IPython and dive deep into interactive computing with IPython. This an advanced guide on interactive and parallel computing with IPython will explore advanced visualizations and high-performance computing with IPython in detail. You will quickly brush up your knowledge of IPython kernels and wrapper kernels, then we'?ll move to advanced concepts such as testing, Sphinx, JS events, interactive work, and the ZMQ cluster. The book will cover topics such as IPython Console Lexer, advanced configuration, and third-party tools. By the end of this book, you will be able to use IPython for interactive and parallel computing in a high-performance computing environment.

What is IPython?

IPython is an open source platform for interactive and parallel computing. It started with the realization that the standard Python interpreter was too limited for sustained interactive use, especially in the areas of scientific and parallel computing.

Overcoming these limitations resulted in a three-part architecture:

  • An enhanced, interactive shell

  • Separation of the shell from the computational kernel

  • A new architecture for parallel computing

This chapter will provide a brief overview of the architecture before introducing some basic shell commands. Chapter 3, Stepping Up to IPython for Parallel Computing, will cover the more advanced features. The parallel architecture will be covered in Chapter 4, Messaging with ZeroMQ and MPI. Before we proceed further, however, IPython needs to be installed.

Those readers who have experience in parallel and high-performance computing but are new to IPython will find the following sections useful in quickly getting up to speed. Those experienced...
