SUMMARY:A Step Ahead: Novel HPC Approaches to provide Early Warnings for S
 evere Weather
DESCRIPTION:Focus Session\n\nA Step Ahead: Novel HPC Approaches to provide
  Early Warnings for Severe Weather\n\nLapillonne\n\nSevere weather warning
 s based on numerical weather prediction models are a public service offere
 d by the government and form part of basic meteorological provision. Accur
 ate and timely warnings play an important role in protecting the public an
 d informing the economic sector. But, the weather and climate community is
  struggling to keep up with the fast-paced developments as HPC system desi
 gns strive towards the Exascale. Only few production-ready community codes
  are able to leverage emerging hardware architectures. This has become kno
 wn as the software productivity gap.  While programming models - such as O
 penACC - are available to target these hardware architectures, they furthe
 r increase the complexity of the code and thus exacerbate the problem. Thi
 s talk summarizes a co-design effort for a regional weather and climate mo
 del that presents an alternative pathway. It will showcase how MeteoSwiss 
 is developing and deploying novel HPC approaches to improve its real-time 
 weather forecasting system. Significant parts of the code have been rewrit
 ten based on a domain-specific language (DSL). The DSL allows a high-level
  hardware agnostic formulation of models of physical processes which can b
 e compiled to different hardware targets. Finally, we will demonstrate the
  capability of the refactored code on the leadership-class heterogeneous H
 PC system Piz Daint in Switzerland -- currently the #3 supercomputer world
 wide -- and discuss the implications for global km-scale weather and clima
 te simulations together with the question of how far do we still have to g
 o to make the next leap forward in weather and climate modeling.\n\nPasses
