Energy Efficiency and Extreme Scaling at LRZ

The Leibniz Supercomputing Centre (LRZ) is offering IT services to the universities of Munich, Bavaria, Germany, Europe and beyond. At the top-level, LRZ hosts SuperMUC, a world-class powerful computing system with more than 155,000 Xeon cores and a peak performance of 3 petaflop/s, soon doubled to more than 6 petaflop/s. Running SuperMUC is not only a challenge in terms of its scale, but also in terms of its energy consumption. The latter is addressed through LRZ's innovative cooling environment, while scaling is the goal of the Extreme Scaling Workshops at LRZ. This talk presents the LRZ, provides an overview of its installations, and discusses the results of the scaling workshops. This lays the groundwork of LRZ's strategy for the future, where applications are scaling up to now frontiers at minimum power consumption.
