HAParaNDA

Accurate solution of time-dependent, high-dimensional PDEs requires massive-scale parallel computing and efficient numerical techniques. Spatial decomposition is particularly challenging in higher dimensions, since the memory requirements for uniform grids with fine enough resolution quickly grow prohibitively large and out of reach even for massively parallel computers. The HAParaNDA-project is an attempt at pushing the limit of tractable problems by using adaptive numerical techniques in time and space together with efficient exponential integrators for propagation in time.
