%X The main aim of the sprint was the stepwise, model-mode based porting of the land surface model QUINCY code to GPUs, in line with the ICON OpenACC style and implementation guide. To achieve this goal, the ICON-Land Standalone Driver was first ported to GPUs, followed by running test cases where the Driver called existing GPU-implementations of JSBACH4 scientific processes. The most important practical outcome of the sprint was the preliminary porting of the QUINCY software modules used for simulations in CANOPY model-mode, in which only biogeophysical processes are enabled. This included setting up host-device data synchronization in the infrastructure subroutines, which are called before and after restart data file I/O, regardless of the model mode.
