Results in terms of scalability were not so good. Thus, the porting and the analysis of the hybrid version (using “mini-apps”) on many core architectures (e.g. Xeon Phi) is needed, before extending the hybrid OpenMP/MPI approach to the entire code, in order to justify the effort of the development. This analysis is carrying out in 2015.

Various data assimilation experiments have been done with this configuration, with various data assimilation systems (e.g. Cosme et al, 2011, Bouttier et al. 2014, Yin et al., 2014). In this context, this configuration appears to be useful for data assimilation users, to couple their own DA system on NEMO and compare their results with thgose obtained on this configuration. SEABASS is also easy to take in hand. Also, it allows to update the configuration status to the future version of NEMO. For these reasons, this configuration is a relevant test case for Data Assimilation.
