Abstract:
OceanVar is a Data Assimilation (DA) software which is being used in Italy within the Mediterranean Forecasting System
(MFS) to combine observational data (Sea level anomaly, sea-surface temperatures, etc.) with backgrounds produced by
computational models of ocean currents for the Mediterranean Sea (namely, the NEMO framework). OceanVAR is based
on a three-dimensional variational approach. We describe computational efforts aimed to design a fully parallel OceanVar
software, based on Domain Decomposition (DD), which involves modification of the variational scheme on each sub domain.
Our approach aims to face to the ever greater multi-level parallelism and scalability of the current and of the next generation
of leadership computing facility systems, while fulfilling the specific requirements of OceanVar within the MFS
