Abstract:   Due to the great importance of accurate weather and climate predictions, world-wide efforts are undertaken to develop high-resolution earth system models. We bring together leading international experts to report on their research efforts with focus on global high-resolution simulations. Reaching high resolutions of the earth system of 1km and below to, e.g., resolve clouds and convective motion, and running these simulations over adequate time intervals for actual predictions does not only require further insights into physics and current models, but it also particularly demands for extreme-scale high-performance computing beyond the capabilities that are currently offered by state-of-the-art supercomputers. In our BoF, an overview on high-resolution weather and climate predictions, their feasibility and potential is given. This will yield insight into current and future computability of the underlying models for experts. It will also target the broader audience with interest in weather and climate simulation. The following speakers have been confirmed: Shiann-Jiann Lin, Geophysical Fluid Dynamics Laboratory, Princeton, USA: Feasibility, fidelity, and accuracy of using a Global Cloud-Resolving Model for operational 10-day weather predictions Hisashi Yashiro, Computational Climate Science Research Team, RIKEN, Japan: Recent Extreme-Scale Simulation Efforts for NICAM Lin Gan/Junfeng Liao, Tsinghua University/National Supercomputing Center Wuxi, China: Climate Modeling and HPC at the NSCC-Wuxi Joachim Biercamp, German Climate Computing Center, Germany: ESiWACE - Towards Extreme-Scale Demonstrators for Weather and Climate Simulation Peter Bauer, European Centre for Medium-Range Weather Forecasts: Scalability and HPC Efforts at ECMWF Rich Loft/John Dennis, University Cooperation for Atmospheric Research: KNL, Xeon, and GPU for high-resolution simulations

Targeted Audience
We target people with an interest in supercomputing and current developments in weather and climate simulation. Since weather and climate predictions are of rather broad interest, the session will not only attract experts from HPC or earth system modeling, but it may also reach a broader audience. Since the challenges we face with regard to high-resolution earth system simulations are currently considered in various international programs (with the project ESiWACE representing a key initiative on this matter in Europe), a rather mixed audience is expected.
