In the green software community we see very often that people use the TDP of the processor as a metric to estimate how much energy the CPU will consume for a specific workload. [...]

A detailed blog article is yet to come, but for everyone who follows our blog only and not our repositories we wanted to highlight that we open sourced the new XGBoost variant of the SPECPower estimation model for cloud workloads on github called Cloud Energy. [...]

We recently had a team of aspiring UX researches at Green Coding Solutions that made a research project on how the Green Metrics Tool can be used. This is a guest article with their results [...]

Last week we have been on the SDIA event for sustainble software and held a workshop on measuring the energy digital products. We presented approchaes where you measure the energy either with tool like Scaphandre or the Green Metrics Tool as well as approaches for restricted environments like the cloud. Here the SDIA DEF Model and our Cloud Energy ML Model where presented. [...]

This arcticle is part of a multi-part series. Be sure to check out / stay tuned for the other parts! A big goal for us here is at how to measure the energy/carbon use of cloud services. [...]

In the past we have joined the Workshop around the Blauer Engel (with the Öko Institut e.V. as the host this year) and also some of the regular meetings from the KDE Eco Team. [...]

In an earlier version of the article the calculation statement contained a message about us being confused why the conversion factor is 277000000. Thanks to Silas Duddeck from the Goethe University in Frankfurt who pointed out that the factor should be 1J = 2,777778⋅10-7kWh = (1/3600000)kWh => 277777777 [...]

In my last blog post I have written about how we finally completed the DC measurement reporter for our Green Metrics Tool. In the last days we have looked at reducing the variance of the ATX powerlanes and finding out if swapping out the resistors for more stable current measurement resistors can improve the measurement. [...]

We finally got our DC measurement setup ready … sadly around one month later than expected. If you wanna see first results go here: Wordpress sample measurement Stress sample measurement If you wann get the details of our journey, why we are integrating it into our tool, some tech specs and the future outlook on when we have the AC measurement ready, then read on :) [...]

Starting this month we will be releasing articles in a regular fashion about insights into energy use of specifc software tools or architectures. In order to lay a foundation to follow these articles we have created at a CO2 Formulas page, where you can find all the relevant formulas how to calculate the energy use of software. Often times software can be directly instrumented and measured, but when the complexity gets too high (in network transmissions) or data is limited (in the cloud) then often assumptions are made.
