Build Supercomputers with Raspberry Pi 3

Summary

In this chapter, we learned how to download and install Ubuntu on the main PC. We wrote and ran a simple serial π code on one core of your PC multi-core processor, and then wrote and ran the first MPI code to call on the cores/processes in the multi-core processor in your PC. Armed with this knowledge/technique, we wrote and ran the MPI code version of the simple serial π code, and in the process learned how the for loop distributes the work/task among the cores in the processor for attaining an ultimate solution. Finally, we employed the MPI coding technique learned to generate the π values from the Euler, Leibniz, and Nilakantha infinite series. In Chapter 3, Preparing the Initial Two Nodes, we will learn how to prepare the initial two ...
