A first look at Structured-Multiscale Algebraic Multigrid for Lattice Field Theory
Pauline Schauerte, Jaime Fabián Nieto Castellanos, Arnold Krechel +2
State-of-the-art solvers for the Dirac equation in Lattice QCD are based on adaptive multigrid methods. These require fine-tuning of many algorithmic parameters to achieve optimal…
Chebyshev smoothing with adaptive block-FSAI preconditioners for the multilevel solution of higher-order problems
Pablo Jiménez Recio, Marc Alexander Schweitzer
In this paper, we assess the performance of adaptive and nested factorized sparse approximate inverses as smoothers in multilevel V-cycles, when smoothing is performed following th…
A Parallel-in-Time Combination Method for Parabolic Problems
Michael Griebel, Marc Alexander Schweitzer, Lukas Troska
In this article, we present a parallel discretization and solution method for parabolic problems with a higher number of space dimensions. It consists of a parallel-in-time approac…
A Multiscale Fracture Model using Peridynamic Enrichment of Finite Elements within an Adaptive Partition of Unity: Experimental Validation
Matthias Birner, Patrick Diehl, Robert Lipton +1
Partition of unity methods (PUM) are of domain decomposition type and provide the opportunity for multiscale and multiphysics numerical modeling. Within the PUM global-local enrich…
