A scalable space-time domain decomposition approach for solving large-scale nonlinear regularized inverse ill-posed problems in 4D variational data assimilation

Luisa D'Amore. Emil Constantinescu, Luisa Carracciuolo

We develop innovative algorithms for solving the strong-constraint formulation of four-dimensional variational data assimilation in large-scale applications. We present a space-tim…

Domain Decomposition in space-time of 4D-VAR Data Assimilation problem: a case study on the ROMS software

L. D'Amore, R. Cacciapuoti, A. Moore

Domain Decomposition of 4D-VAR Data Assimilation (DD-4DVAR) is made up of decomposition of the spate-time domain, solution of reduced forecast model and minimization of local 4D-VA…

A Multilevel Approach for the Performance Analysis of Parallel Algorithms

Luisa D'Amore, Valeria Mele, Diego Romano +1

We provide a multilevel approach for analysing performances of parallel algorithms. The main outcome of such approach is that the algorithm is described by using a set of operators…
