There are various ways to ensure green software – tracking its energy consumption is one of the ways but practitioners often find it hard to start in this direction. In this article, we are going to cover 7 different ways of measuring the energy consumption of your code. There is not a single approach since different platforms require different strategies. This article will help you skip that part of the deal and start measuring energy right away! Power Monitors vs Energy Profilers For example, some tools only work with Intel CPUs, other only work with a particular OS, and so on.Įvery time I want to measure energy consumption, I have to study a ton of different tools before I find the right power tool that works with my software system. The most accurate strategy to measure energy consumption is using power monitors – hardware tools that connect to the power source of your device or component and measure the actual power leveraged at any instant of time.ĭespite being extremely precise, power monitors are also extremely difficult to set up. Often, they require you to make custom changes to your computer device.

My setup to measure the energy consumption of Android apps using a power monitor device. What’s more, you will need to find a way of time-syncing the power data with the execution of your software. Some power monitors are shipped with a software library that allows controlling the power monitor from your computer – starting, stopping, collecting measurements. The problem takes another level if you are working with a team of developers that should also run some energy tests in their local workstations.

I have previously written about how to use a Power Monitor to measure energy consumption and is not easy at all: you have to do all sorts of hardware hacks before you can make reliable measurements.īut don’t give up just yet. Energy profilers have come to our rescue – they do not require any special hardware or fancy power sensors. They typically have an estimation model of the power cost of the different hardware components. Based on which components are active during execution, the profiler estimates a particular energy cost.Įnergy profilers are usually shipped as easy-to-use tools that you can simply run from any device to get a final number: the total energy consumption. It is easy to time sync with your software execution: you start the profiler when you start the execution and you stop it when the execution ends.
Since energy profilers rely on estimations, they can only operate under very specific environments. Hence, there is no one-size-fits-all energy profiler and finding one that works for a given case is far from trivial.īelow I select a few energy profilers I have used in the past and I explain how to get started with them.
