Abstract: The objective of the sprint was to address two technical challenges: evaluating and optimizing the performance of PDAF software modules, and developing a strategy for porting the code to GPUs. The key results achieved during the sprint are an evaluation of the parallel efficiency of a standalone application of the ICON-Ocean model with PDAF, code analysis, and the development of a strategy for GPU offloading. Preliminary GPU porting of core PDAF subroutines and subsequent performance testing were also carried out.
