Implementation of NEMO global 1km ocean-only demonstrator and performance analysis (D2.10)
Popularity of one kilometre scale global geophysical models is continuously growing in Europe. In this study, we increase the resolution of the NEMO ocean model, to better identify technical limitations of the present implementation and deduce, from the performance measured on one of our top superco...
