Delayed approximate matrix assembly in multigrid with dynamic precisions
Charles D. Murray, Tobias Weinzierl
The accurate assembly of the system matrix is an important step in any code that solves partial differential equations on a mesh. We either explicitly set up a matrix, or we work i…

Stabilised Asynchronous Fast Adaptive Composite Multigrid using Additive Damping
Charles D. Murray, Tobias Weinzierl
Multigrid solvers face multiple challenges on parallel computers. Two fundamental ones read as follows: Multiplicative solvers issue coarse grid solves which exhibit low concurrenc…
