I am the main developer of the global ocean-sea-ice model ICON-O. I am responsible for model design, architecture and implementation. The model code consists of ~50 000 lines of object-oriented Fortran-code. The parts on the discretization of the ocean model equations and the subgridscale closure were written by myself. The coding of technical infrastructure such as high-end optimization or reading/writing of huge datasets was done by scientific programmers under my advice. The model code runs efficiently on High-Performance Computing architectures such as the petascale supercomputer of the German Climate Computing Center (DKRZ), the Jülich Supercomputing centre or the Supercomputing Centre of the German Weather Service DWD. Preparations are ongoing to run the ICON code on other new supercomputers such as LUMI in Finland, the fastest supercomputer in Europe.
