The power gadget collects power data every 100ms. What command would you put if you wanted to change the energy counter sampling resolution from the default which is 100ms? Say we want to log every 2 seconds, what command would be used and why would you want to log every 2 seconds rather than every 100ms?
- [Voiceover] Here's a two-part…challenge question to get you more familiar…with using the Intel Power Gadget.…The first part of that question is…The Intel Power Gadget, by default,…collects a sample every 100 milliseconds.…What command would you put in the command line…version of the tool to change the rate at which…the energy counters on the processor are read?…Meaning you wanna change that sampling rate…from the default of 100 milliseconds.…The next part of that question is…say we want to read a sample every two seconds,…rather than every 100 milliseconds.…
What command would you put…to change the sampling rate to two seconds?…More importantly, why would you wanna read a sample…every two seconds versus every 100 milliseconds?…So think about that.…A big hint is to look at the Intel Power Gadget…user guide for hints.…The command line options are in there.…
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.
