In the conclusion of the Intel Power Gadget tool you are reminded of the techniques applied to the demo application and how to use these techniques on your own application. Aside from these reminders, you will be pointed to resources that will help you further improve your power profiling skills with the Intel Power Gadget as well as some homework assignments to try.
- [Voiceover] In short, we can use the Intel Power Gadget…to find out if one of our applications…is power-hungry or not.…We did this by first setting up…our Power profiling environment.…That included closing any applications…that did not need to be open.…Also, because our DirectX 11 jigsaw puzzle application…did not need the internet,…we put the system into airplane mode.…This disabled most of the background services…that would otherwise be consuming power.…Do the same on your end.…If your application under test does not need the internet,…disable those background services…by putting your system into airplane mode.…
After we set up our environment,…we went to the powerlog command…where we used this command…with these command line options.…There are more command line options…available to you in the user guide.…Play around with it, go through the user guide…to become more familiar with…the Intel Power Gadget tool itself…and to find the command that suits your needs.…After we executed that powerlog command,…we then started post-processing the data that was collected.…
With these diagnostic tools and some efficient programming, you can reduce your app's power consumption while improving its response times. In this course, Thomas Pantels introduces a handful of tools used to measure and optimize power consumption. You will see demos on how to use the Intel Power Gadget, Windows Performance Toolkit, TypePerf, and SoC Watch, along with some simple coding tips for making any Windows app more energy efficient.
