Daniel Ganellari (KFU, advisor G. Haase): Fast many-core solvers for the Eikonal equations in cardiovascular simulations

Abstract: We develop a framework similar to the Fast Iterative method by Kirby, for solving the Eikonal equation for tetrahedral meshes, but with many differences especially in the algorithmic structure for streaming processor architectures. We reformulated the original approach in three steps: (1) precompute distances/angles w.r.t. velocity metric per element, (2) local Gray code numbering to access precomputed distances/angles, (3) significant reduction of memory footprint by determining angles from distances. I will show the detailed data structures and algorithms for streaming architectures and how does the careful management of data allows a higher computational density on the GPU.[hide abstract]
