In this talk we will explore the use of OpenCL on GPUs for the implementation of the dynamical core of the ICON model as a possible alternative to the classical CPU based counterpart.
We first discuss the potential performance issues of the solver with the help of the roofline model, a visual tool which guides the optimization process.
Then, the performance results of an initial implementation will be presented and a possible role for the GPU will be outlined.
