Appendix A Solutions

In this appendix you will learn how to answer all those nagging questions the easy way.

A.1 Overview

Exercise 1.1 Examine your computer system and clarify how many nodes it has, what node types are available, and by what network(s) they are connected.

The Lenovo P50 I am writing this book on is a full-featured single-node engineering workstation. The cluster I am using for test runs involving networking is so special that I do not feel that I can describe it here.

Exercise 1.2 Examine your computing nodes and find out what kind of processor(s) they exhibit, how many cores and threads they run, what memory type and what caches they use, and what networking and graphics capabilities they have.

The Lenovo P50 laptop mentioned ...

Julian F.

Head of Cybersecurity

I wanted to learn C and C++, but it didn't click for me until I picked up an O'Reilly book. When I went on the O’Reilly platform, I was astonished to find all the books there, plus live events and sandboxes so you could play around with the technology.

Addison B.

Field Engineer

I’ve been on the O’Reilly platform for more than eight years. I use a couple of learning platforms, but I'm on O'Reilly more than anybody else. When you're there, you start learning. I'm never disappointed.

Amir M.

Data Platform Tech Lead

I'm always learning. So when I got on to O'Reilly, I was like a kid in a candy store. There are playlists. There are answers. There's on-demand training. It's worth its weight in gold, in terms of what it allows me to do.
