“Challenges on Extreme Scale Computers - Complexity, Energy, Reliability”

Dr. Dieter Kranzlmüller

Ludwig-Maximilians-Universitaet Muenchen (LMU), Germany


The Leibniz Supercomputing Center (LRZ) in Garching near Munich hosts SuperMUC, a world-class powerful high-performance computer built from more than 230.000 x86-cores. While the theoretical peak performance is more than 6 PetaFlops, the sustained performance of real-world applications is obviously much smaller.

The reasons for this are manifold, and represent substantial challenges for the users. Besides scalability, the inherent complexity of the system, its energy consumption, and the reliability of its components have to be taken into account. With a series of workshops, we tried to address these issues for selected users in order to understand and improve the current situation.

This talk describes the system and its characteristics, as well as the lessons learned from the workshop series. As one outcome, we formulate the necessity of a partnership approach called piCS.


Dieter Kranzlmueller is full professor of computer science at the Ludwig-Maximilians-Universitaet Muenchen (LMU), director of the Leibniz Supercomputing Centre (LRZ) of the Bavarian Academy of Sciences and Humanities, and member of the board of the Center for Digital Technology & Management (CDTM). He is founding member of the Executive Board of the Organisation and German representative on the European Grid Initiative (EGI) Council.

He chairs the MNM-Team (Munich Network Management Team), which is engaged in networks and distributed systems in general, and networks, grids, clouds and HPC in particular.
