The LRZ Extreme Scaling Workshops - How to push the barrier by pushing the user?

Dieter Kranzelmueller (Ludwig-Maximilians-Universitaet Muenchen and Leibniz Supercomputing Centre, Germany)

Scaling applications to higher and higher numbers of cores on supercomputers has been an ongoing race for the last decades. While pessimists have more than once declared the ultimate frontier for scaling, technologies and the human scientists have been pushing further and further. The LRZ Extreme Scaling Workshop series is a means to supporting this endeavor, providing incentives to the user and the technical environment for upscaling of applications. The results demonstrate not only the feasibility and success of the approach, but also the learning curve of the participants and the necessity to invest more in the human capabilities of supercomputing. And then, there are are those applications which scale but still do not fit to the existing architectures. This talk provides an update to the latest findings and results.

Univ.-Prof. Dr. Dieter Kranzlmueller is full professor of computer science at the Ludwig-Maximilians-Universitaet Muenchen (LMU), member of the board of the Leibniz Supercomputing Centre (LRZ) of the Bavarian Academy of Sciences and Humanities, and member of the board of directors of the Center for Digital Technology & Management (CDTM). He is founding member of the Organization and 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. He has been involved in leading roles in numerous EC-funded, international and national projects, including his role as chairman of the e-Infrastructure Reflection Group (e-IRG), Deputy Director of EGEE-II, member of the Executive Board of, and Project Director of EGI-DS. At present, he serves as the general chairman of the ACM Symposium on Virtual Reality Software and Technology (VRST 2016).
