IT Energy

Will we ever be able to accurately assess the carbon footprint of IT? Could a relational footprint methodology be more useful? Paper notes on Pasek et al (2023).

In October 2022 I started a DPhil (PhD) in Engineering Science researching sustainable computing at the University of Oxford.

Puritan value judgments don’t help and any analysis based on concepts of digital sobriety or arbitrary definitions of waste should be rejected.

Notes on the paper Khan et al (2018) RAPL in Action: Experiences in Using RAPL for Power Measurements. Advantages and limitations of the Running Average Power Limit (RAPL) interface.

Removing the aggregation spine resulted in 5x higher speed and capacity, and 41% reduction in power.

Developers need metrics that are consistent and easy to optimize, but carbon intensity varies in time and space. So when is it a useful metric for developers to consider?

Firefox 104 introduces power consumption measurement in the profiler. What does this mean for analyzing website energy consumption?

This is a good paper that makes valid points about the possibilities of migrating flexible IT workloads, however it makes classic assumptions I see in most papers that discuss this topic.

Which languages are the fastest and most energy efficient? The simple answer is: C, C++, Rust. The accurate answer is: it depends.
