The Cognixia Podcast explores emerging digital technologies and this episode discusses a breakthrough in data center energy efficiency. Data centers consume vast amounts of electricity, contributing to 2% of global emissions. Researchers at the University of Waterloo have discovered that modifying 30 lines of code in the Linux kernel's network stack can cut energy consumption by 30%. This technique, called "interrupt request suspension," reduces CPU interruptions during high-traffic periods, improving efficiency and performance. Implementing this change could significantly reduce costs and environmental impact without requiring major infrastructure changes, paving the way for energy-conscious software development in the future.
