By: Thomas Bitterman, Dipanjan Deb

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.

Chapter 4. Messaging with ZeroMQ and MPI

This chapter covers messaging and its use in parallel programming. Unlike threading, a system that utilizes multiple processes does not have a single memory area that the entire system can access. This means that if different subprocesses are to communicate, they must pass data back and forth in the form of messages. In this chapter, we will introduce and discuss two popular message passing mechanisms: ZeroMQ and MPI.

The following topics will be covered:

  • The storage hierarchy address spaces, and data locality

  • Concepts of ZeroMQ

  • Messaging patterns in ZeroMQ

  • Concepts of MPI

  • Messaging patterns in MPI

  • MPI and process control
