Dutch Computational Science Day 2023

The Dutch Computational Science Day (DUCOMS) will take place in Utrecht the 10th of November 2023, and we are giving a talk on "Energy-efficient computing".

From large-scale experiments and simulations, to analyzing and visualizing data, the use and development of software is nowadays an integral part of the job routine for many scientists. Running this software, no matter if on a laptop, the cloud, or a supercomputer, has a cost in terms of energy. While in the past this cost was mostly a concern for the provider, the rising cost of electricity combined with the increased power requirements of supercomputers, now in the megawatt range, have resulted in some providers passing this cost on to the users. This fact, paired with the ongoing effort to reduce the environmental impact of science and its carbon footprint, is forcing the scientific community to reduce the energy consumption of their software. Traditionally, optimizing time to solution was considered the optimal way to also reduce energy consumption. However, new results suggest that this is not always the case, and that optimizing directly for energy efficiency can reduce overall energy consumption without compromising performance. In this talk, we will highlight tools and techniques that we use at the Netherlands eScience Center to improve the energy efficiency of the code we work on, and provide examples of the results we have achieved in recent years.

Registration is open.
