Most of the global and regional climate models only run on high performance computers that are connected to expensive computing centers. Therefore, access to climate models and the required computing facilities is limited to a small number of institutions. On the other hand, modern desktop computers are getting faster, theoretically allowing to run long-term simulations.
In our contribution to the SASSCAL project, we investigated the advantage of using a common graphics card to shorten the time needed for a simulation. Thus, we reprogrammed the existing regional climate model REMO (Jacob, 2001) in a way that parts of the calculations are sourced out to graphical processing units. Additionally, in order to provide non-climate scientists in the SASSCAL region better access to the model, a user-friendly model version has been developed. This version is preconfigured for the SASSCAL region and possesses a graphical user interface.
