PRACE-ISC Award 2014 goes to sustained petascale seismic science on SuperMUC

On Monday 23 June 2014 at 13:15 during the Opening Session (http://www.isc-events.com/isc14_ap/sessiondetails.htm?t=session&o=1&a=select&ra=byday) of the 2014 edition of the International Supercomputing Conference (ISC) in Leipzig, Germany, the PRACE-ISC Award will be presented to Alexander Breuer, TU München; Alexander Heinecke, TU München; Sebastian Rettenberger; TU München; Michael Bader, TU München; Alice-Agnes Gabriel, LMU München; Christian Pelties, LMU München for their paper entitled “Sustained Petascale Performance of Seismic Simulations with SeisSol on SuperMUC”

PRACE, the Partnership for Advanced Computing in Europe, awards a prize to the best paper submitted to the ISC Research Paper Sessions and the PRACE Scientific Conference in one of the following areas:

·         a breakthrough in science achieved through high performance computing

·         an algorithm or implementation that achieves a significant improvement in scalability or performance

·         a novel approach to performance evaluation on a massively parallel architecture

The PRACE Scientific Steering Committee (SSC, see here: http://www.prace-ri.eu/Organisation) selects the paper to receive the Award, which will be presented at the ISC Opening Session on Monday 23 June 2014 at 13:15. The winner of the PRACE ISC Award will receive sponsorship for participation in a training event, or a conference relevant to petascale computing.

“Seismic simulations in realistic 3D Earth models require peta- or even exascale compute power to capture small-scale features of high relevance for scientific and industrial applications. In this paper, we present optimizations of SeisSol — a seismic wave propagation solver based on the Arbitrary high-order accurate DERivative (ADER) Discontinuous Galerkin method on fully adaptive, unstructured tetrahedral meshes — to run simulations under production conditions at petascale performance. Improvements cover the entire simulation chain: from an enhanced ADER time integration via highly scalable routines for mesh input up to hardware-aware optimization of the innermost sparse-/dense-matrix kernels. Strong and weak scaling studies on the SuperMUC machine demonstrated up to 90% parallel efficiency and 45% floating point peak efficiency on 147k cores. For a simulation under production conditions (108 grid cells, 4.8*1010 degrees of freedom, 5 seconds simulated time), we achieved a sustained performance of 1.09 PFLOPS,” says Alexander Breuer.
