Book excerpt: A step-by-step guide that will enhance your skills in creating powerful systems to solve complex issues About This Book Carlos R. Morrison from NASA will teach you to build a supercomputer with Raspberry Pi 3 Deepen your understanding of setting up host nodes, configuring networks, and automating mountable drives Learn various math, physics, and engineering applications to solve complex problems Who This Book Is For This book targets hobbyists and enthusiasts who want to explore building supercomputers with microcomputers. Researchers will also find this book useful. Prior programming knowledge is necessary; knowledge of supercomputers is not. What You Will Learn Understand the concept of the Message Passing Interface (MPI) Understand node networking. Configure nodes so that they can communicate with each other via the network switch Build a Raspberry Pi3 supercomputer. Test the supercluster Use the supercomputer to calculate MPI p codes. Learn various practical supercomputer applications In Detail 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. Style and approach A progressive guide that will start off with serial coding and MPI concepts, moving towards configuring a complete supercluster, and solving real world problems
