Weather forecasting is both one of the most visible as well as one of the more demanding applications of computing in the world we know today. The development of forecasting models draws heavily on parallelization and efficient exploitation of many-core systems to get predictions done in near real-time. Because the computational domain is very large when using high resolution models, domain decomposition over many nodes using distributed memory parallel programming paradigms are a necessity. Toon Moene of the Royal Dutch Meteorological Institute KNMI will tell us how modern models such as HIRLAM and HARMONIE exploit advances in computing, having run these models also on his home PC - catching several meteorological errors in the process. Toon Moene is a researcher at KNMI, member of the Technical Advisory Committee to the Council of the European Centre for Medium Range Weather Forecasts ECMWF, and member of the GCC Steering Committee and the Fortran Standardization Committee.
