Numerical Weather Prediction - Facing the Future with C++
Explore a comprehensive keynote address from C++Now 2015 on Numerical Weather Prediction (NWP) and its future with C++. Delve into the challenges faced by the NWP community, including data-intensive processing, tight time constraints, and the need to modernize software techniques for many-core era hardware. Learn about the transition from monolithic Fortran code to embracing modern software practices, with a focus on high-performance languages like C++ and Domain-Specific Languages (DSLs). Discover how the European Centre for Medium-Range Weather Forecasts (ECMWF) is addressing these challenges, including the development of a C++ Domain-Specific Embedded Language (DSEL) inspired by functional programming for building parallel processing pipelines for meteorological data. Gain insights into the future of NWP software development, including power limitations, data I/O rates, and exponential volume growth, as well as the benefits and challenges of implementing C++ in scientific computing environments.
