| Popis: | This research focuses on designing a high-speed scheme for tsunami modelling using nested computing. Computations are carried out on a sequence of grids composed of geographical areas with resolutions where each is embedded within another. This decreases the total number of calculations by excluding unimportant coastal areas from the process. The paper describes the distributed streaming computational scheme allowing for flexible reconfiguration of heterogeneous computing resources with a variable set of modelling zones. Computations are implemented by distributing these areas over modelling components and by synchronising the transitions of boundary data between them. Results of numerical modelling experiments are also presented. |
