ENVIRONMENT AND ENERGY

Supported by the experts of the Leibniz Supercomputing Centre (LRZ), computer scientists, mathematicians, and geophysicists of the Technische Universität München (TUM) and the Ludwig-Maximilians-Universität München (LMU) collectively optimised and completely parallelised the 70,000 lines of code of SeisSol, a software to simulate earth quakes, to optimally leverage the parallel architecture of SuperMUC.

The collaborative effort under leadership of Prof. Dr. Michael Bader (TUM) and Dr. Christian Pelties of the Department of Geo and Environmental Sciences of LMU resulted in achieving a SeisSol application performance of 1.42 Petaflops for a weak scaling test which corresponds to 44.5% of SuperMUC’s peak processing performance. For the entire simulation run, which took about 3 hours of computing time on the LRZ supercomputer, a sustained system performance of 1.09 Petaflops was achieved.
