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.

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.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
