Economic Observations of the Leibniz Supercomputing Centre

摘要

Abstract The Leibniz Supercomputing Centre (LRZ) is home of SuperMUC-NG, one of the top 10 supercomputers of the world, and offers its computing capabilities to scientists in Bavaria, Germany and Europe. However, its task is more holistic in providing generic IT-services for sciences, including everything from the desktop of the scientist via arbitrary cloud services to the large-scale high performance computer. This talk addresses the economical aspects of LRZ as an example from academia, where key performance indicators are scientific output and not stakeholder revenue. We will take a look at actual costs of the services, accounting of user activities, and sustainability measures for the future. As power usage is a large cost factor, LRZ is also leading in energy-efficient computing with hot-water cooling and heat reuse. Supercomputer; Cloud; Power usage; Sustainability; Leibniz; Heat reuse
