Аннотация
We present recent modifications of the SL-AV global atmosphere model parallel structure and algorithms. The modification of the hybridMPI+OpenMP parallelization structure as well as new parallel I/O system is described. The new multigrid algorithm for solving the linear algebraic equations systems arising from discretization at the reduced latitude-longitude grid is introduced and the convergence results for this method are presented.
