Towards a sustainable ET Computing Center — •Stefan Krischer and Achim Stahl — RWTH Aachen University, III. Physikalisches Institut B

For the Einstein Telescope, a dedicated computing center will be required to support detector control, low-latency data processing, and parts of the offline analysis. In preparation, the infrastructure is being explored with a strong focus on sustainability. To assess feasibility, a prototype computing facility is being developed with its own renewable energy system capable of supplying 100% locally generated power. In this setup, computing workloads and hardware adapt their power consumption to the instantaneous energy availability, reducing the required energy-storage capacity. We present the concept and initial insights from the prototype development as a basis for a more sustainable computing center for the Einstein Telescope.
