Users help shaping the path to a sustainably operated VISPA computing cluster — Niclas Eich, Johannes Erdmann, Martin Erdmann, Benjamin Fischer, •Paul Gilles, Tim Hauptreif, and Jan Kelleter — RWTH Aachen University

As climate change progresses, it is evident that computing for physical research needs to become more sustainable. Although the capacity of renewable energy resources is increasing every year, we are currently still dependent on the use of fossil electricity generation. Due to the dynamic nature of renewable energy, it is essential to target smart, adaptive power consumption for more sustainable research.

In this talk, we will present approaches and results within the VISPA project to show users their personal energy consumption in the computing cluster and enable them to automatically schedule their HTCondor jobs based on the availability of renewable energy. We also present our digital twin of the VISPA cluster, which is primarily used to develop and test new resource-saving planning methods.
