Highly Scalable Algorithms for the Sparse Grid Combination Technique

Strazdins, Peter; Ali, Muhammad; Harding, Brendan

Description

Many petascale and exascale scientific simulations involve the time evolution of systems modelled as Partial Differential Equations (PDEs). The sparse grid combination technique (SGCT) is a cost-effective method for solve time-evolving PDEs, especially for higher-dimensional problems. It consists of evolving PDE over a set of grids of differing resolution in each dimension, and then combining the results to approximate the solution of the PDE on a grid of high resolution in all dimensions. It...[Show more]
