This paper presents the GPU porting through OpenACC directives of the Dutch Atmospheric Large-Eddy Simulation (DALES) application, a high-resolution atmospheric model. The code is written in Fortran 90 and features parallel (distributed) execution through spatial domain decomposition. We assess the performance of the GPU offloading, comparing the time-to-solution on regular and accelerated HPC nodes. A weak scaling analysis is conducted and portability across NVIDIA A100 and H100 hardware is discussed. Finally, we show how targeted kernels can benefit from further optimization with Kernel Tuner, a GPU kernels auto-tuning package.

This manual is primarily designed for and by teachers for use in education, but should be a useful resource for anyone interested in creating and collaborating on Jupyter book. Our aim is to provide a simple way to start book-making for new users (it only takes 10 clicks!) through advanced usage for experienced users. We hope you find this resource useful and refer back to it often.
