Today the PASC18 conference announced that Nils P. Wedi from ECMWF will be one of its keynote speakers. The talk will be entitled,”From Weather Dwarfs to Kilometre-Scale Earth System Simulations.”

The European Centre for Medium-Range Weather Forecasts (ECMWF) leads a number of Horizon 2020 activities (ESCAPE) with innovation actions for developing a holistic understanding of energy-efficiency for extreme-scale applications using heterogeneous HPC architectures by: (a) defining and encapsulating the fundamental algorithmic building blocks (“Weather and Climate Dwarfs”) underlying weather and climate services; (b) combining frontier research on algorithm development with hardware adaptation using DSLs; (c) developing benchmarks and cross-disciplinary Verification, Validation, and Uncertainty Quantification (VVUQ) for weather and climate applications; and (d) synthesizing the complementary skills of global numerical weather prediction with leading European researchers.

This talk will illustrate the need for and practicality of producing ensembles of km-scale simulations, summarize progress on accelerating state-of-the-art global weather and climate predictions, and discuss outstanding issues and future directions on producing and analyzing big weather data while balancing time-critical customer needs with energy- and time-to-solution.

Nils P. Wedi has a PhD from Ludwig-Maximilian University of Munich and joined ECMWF in 1995. His career at ECMWF encapsulates a diverse range of work both technical and scientific. He leads ECMWF’s Earth System Modeling section that addresses all aspects of scientific and computational performance relating to ECMWF’s forecast model and the ensemble forecasting system. He develops strategies to secure the scalability of the model on future high-performance computing systems. He is the scientific coordinator of the European H2020 projects ESCAPE and ESCAPE-2 to address the challenges of rising energy cost for computing towards affordable, exascale high performance simulations of weather and climate, and he is a member of the World Meteorological Organization working group on numerical experimentation (WGNE).

PASC18 takes place July 2-4 in Basel, Switzerland.

In related news, the deadline for PASC18 Student Travel Grant Applications is Feb. 14, 2018.
