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.

Preparing the master node

During bootup, select the US or (whatever country you reside in) keyboard option located at the middle-bottom of the screen. After bootup completes, start with the following screenshot. Click on Menu, and then Preferences. Select Raspberry Pi configuration (see the following screenshot):

Menu options

The System tab appears (see the following screenshot). Type in a suitable Hostname for your master Pi. Auto login  is already checked:

System tab

Go ahead and Change Password to your preference (see the following screenshot):

Change password

Select the Interfaces tab (see the following screenshot). Click  Enable on all options, especially Secure Shell (SSH), as you will be remotely logging into the Pi2 or Pi3 from your main PC. The other options are enabled for convenience, as you may be using the Pi2 or Pi3 in other projects outside of supercomputing:

Interface options

The next important step is to boost the processing speed from 900MHz to 1000 MHz or 1 GHz (this option...
