I attended the first half of the mini-symposium. I liked the concept of the session, to see how the vendors would optimize the cloudsc mini-app. It ended up being sort of like this: Nvidia (OpenACC, CUDA), AMD (OpenMP, HIP), Intel (OpenMP, SYCL).
The last presentation advocated a different approach, based on a data-centric programming model, supported by a Python framework called DaCe. This was the related to a previous thread: Fortran is dead – Long live Fortran!
