Extreme Energy Efficiency with SuperMUC
Prof. Dr. Arndt Bode, Director, Leibniz Rechenzentrum & Technische Universität München
SuperMUC is the latest high performance general purpose computer system installed at the Leibniz Supercomputer Center of the Bavarian Academy of Sciences and Humanities (LRZ-BAdW) in Munich.
It is the contribution of the Gauss Centre for Supercomputing GCS to the Partnership for Advanced Computing in Europe PRACE and will be used by European and German scientists.
The SuperMUC is based on the IBM Blade Center System and consists of more than 150.000 Intel Sandybridge cores with over 300 Terabytes of memory and around 3 Petaflops Peak performance. It is embedded into a general purpose user environment including long term storage and a new visualization center. It is expected to be expanded in 2014/5.
Special emphasis with SuperMUC is for extreme energy efficiency. For that purpose the computer center infrastructure was equipped with a warm liquid cooling loop serving the direct liquid cooling technology of the IBM system. Fine grained energy monitoring at all levels of the system and the building infrastructure will enable tools to further optimize energy consumption by using processor throttling techniques and other optimizing measures. The talk gives an overview on the system and the planned developments for energy efficiency.
