Высокопроизводительные вычисления, параллельные методы и алгоритмы в задачах геофизики
In order to perform large scale numerical simulation of wave propagation in 3D heterogeneous multiscale viscoelastic media, Finite Difference techniques and its parallel implementation based on domain decomposition is used. A typical statement of borehole geophysics are dealt with - crosswell measurements. This statment is essentially multiscale, that is claims to take into account heterogeneities of very different size in order to provide reliable results of simulations. Locally refined spatial grids help us to avoid use of redundantly tiny grid cells in a target area, but cause some troubles with uniform load of Processor Units involved in computations. We present results of scalability tests together with results of numerical simulations for both statements performed for some realistic models.
