This is a proposal for a two-month research visit to the Disaster Prevention Research Institute of the University of Kyoto in Japan, to work with Prof. Tetsuya Takemi of the Atmospheric and Hydrospheric Disasters Division on hardware acceleration of simulations of extreme weather events. Hardware acceleration means the use of special hardware -- in our case General-Purpose Graphics Processing Units (GPGPUs) and Field-Programmable Gate Arrays (FPGAs) to speed up a computational task. In particular, our aim is to reduce the simulation times for models using the Weather Research and Forecasting (WRF) model, the leading next-generation model for weather and climate simulations. This will allow the models to be run at higher precision, which is essential in the prediction of extreme weather events. The main purpose of this research visit is to lay the groundwork for a long-term collaboration including research groups in Japan and the UK, with the aim of accelerating the full Weather Research and Forecasting (WRF) model and adding support for FPGA acceleration.
