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.

A. Appendix

Write/run serial π code

Using your PC as a one-node supercomputer is quite easy, and can be quite a fun exercise as you command the cores in the processor to do your digital bidding. From here on, it will be assumed that the reader has a working knowledge of the C language. So, the first step on your digital journey will be to write and run a simple C code to compute π. This code will perform numeric integration (using 300,000 iterations) on an x function representation of π. You will then convert this code's logic into its MPI version, run it on one core of the processor, and then gradually bring online the remaining cores. You will observe progressively improving processing speed as you activate successive cores. Let's start with the simple π equation:

Write/run serial π code

This equation is one of many that are available for obtaining an approximate value of π. In later sections, we will explore a few more complex and famous equations that will give your supercomputer...
