Description
Given the large amounts of experimental data in ErUM (Research of Universe and Matter), the importance of scientific computing for ErUM – especially with respect to sustainability issues related to procurement and operation, for instance the CO$_2$ footprint – cannot be understated. In order to advance the environmentally sustainable aspects of scientific computing for ErUM, the BMFTR-funded SUSFECIT (Sustainable Federated Compute Infrastructures) research network has been recently established. Research partners include DESY, KIT, Öko-Institute and the universities in Aachen, Bonn, Freiburg and Göttingen. The core idea is to incorporate information on energy mix, cost and embedded carbon in scheduling decisions of federated, non-localised, compute infrastructures like the network of German WLCG sites and make those infrastructures more dynamic and responsive to those aspects. Specific research-areas within SUSFECIT have been tasked with information collection and forecasting, orchestration of resources, accounting, and a digital twin for simulations and optimisation studies. The poster will provide an overview of the project and discuss its concepts and exploratory work.
