Raspberry Pi Super Cluster

By: Andrew K. Dennis

Overview of this book

A cluster is a type of parallel/distributed processing system which consists of a collection of interconnected stand-alone computers cooperatively working together. Using Raspberry Pi computers, you can build a two-node parallel computing cluster which enhances performance and availability. This practical, example-oriented guide will teach you how to set up the hardware and operating systems of multiple Raspberry Pi computers to create your own cluster. It will then navigate you through how to install the necessary software to write your own programs such as Hadoop and MPICH before moving on to cover topics such as MapReduce. Throughout this book, you will explore the technology with the help of practical examples and tutorials to help you learn quickly and efficiently. Starting from a pile of hardware, with this book, you will be guided through exciting tutorials that will help you turn your hardware into your own super-computing cluster. You'll start out by learning how to set up your Raspberry Pi cluster's hardware. Following this, you will be taken through how to install the operating system, and you will also be given a taste of what parallel computing is about. With your Raspberry Pi cluster successfully set up, you will then install software such as MPI and Hadoop. Having reviewed some examples and written some programs that explore these two technologies, you will then wrap up with some fun ancillary projects. Finally, you will be provided with useful links to help take your projects to the next step.

Power for multiple devices

In this section we take a brief look at some alternatives to using standard micro-USB phone-style chargers or desktop-mounted USB ports for powering your Raspberry Pi.

Each of the following suggestions should provide you with some ideas for future projects and provide some links to further reading. Remember, when working with mains electricity, to always make sure you take the necessary safety precautions and refer to a licensed professional.

USB wall plates

One alternative to the standard USB hubs is to install a wall mounted USB plate.

For running a small number of Raspberry Pis you can eliminate the need to use a USB hub or to use a desk-mounted multi adapter with USB ports.

Wall plates are directly wired into your mains electric as with a standard electricity socket.

These can be found at most home DIY stores. It is recommended that you have them installed by a certified electrician due to the risk of electric shock posed by working with mains electricity. Some plugs...
