Build Supercomputers with Raspberry Pi 3

By: Carlos R. Morrison

Overview of this book

Author Carlos R. Morrison (Staff Scientist, NASA) will empower the uninitiated reader to quickly assemble and operate a Pi3 supercomputer in the shortest possible time. The lifeblood of a supercomputer, the MPI code, is introduced early, and sample MPI code provides additional practice opportunities for you to test the effectiveness of your creation. You will learn how to configure various nodes and switches so that they can effectively communicate with each other. By the end of this book, you will have successfully built a supercomputer and the various applications related to it.

Linux installation

Before we embark on our digital odyssey, the reader is advised to install the Linux OS on their main PC as we will be using command-line instructions to communicate remotely with your Pi2 or Pi3, via Secure Shell (SSH) protocol (more on this later). You may visit the Ubuntu website: http://www.ubuntu.com/download/desktop/install-ubuntu-desktop for tutorial/instructions, and download a free version of the OS. In addition, when installing Ubuntu, select the option that allows you to access the Windows OS as you also will eventually be using Windows apps such as win32 Disk imager, and an SD card formatter (we will discuss their download and applications later when you begin configuring your eight-node Pi2 or Pi3 super cluster).
