Software Design X-Rays

Exercises

The following exercises are designed to let you explore architectural hotspots on your own. By working through the exercises you also get the opportunity to explore an additional usage of complexity trends to supervise unit test practices.

Prioritize Hotspots in CPU Architectures

• Repository: Linux^[74]
• Language: C
• Domain: The Linux kernel is an operating system kernel.
• Analysis snapshot: https://codescene.io/projects/1740/jobs/4358/results/code/hotspots/system-map

In this chapter we focused our case study on the gpu package since it was the top hotspot. Once we’re done with that analysis it’s time to move on to the next candidate: the arch package. Located in the top folder of Linux, the arch directory contains a module for each supported ...
