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.},
