Local Fourier Analysis of Multigrid Methods with Polynomial Smoothers and Aggressive coarsening
James Brannick, Xiaozhe Hu, Carmen Rodrigo +1
We focus on the study of multigrid methods with aggressive coarsening and polynomial smoothers for the solution of the linear systems corresponding to finite difference/element dis…
Bootstrap Algebraic Multigrid for the 2D Wilson Dirac system
James Brannick, Karsten Kahl
We develop an algebraic multigrid method for solving the non-Hermitian Wilson discretization of the 2-dimensional Dirac equation. The proposed approach uses a bootstrap setup algor…
Aggregation-based aggressive coarsening with polynomial smoothing
James Brannick
This paper develops an algebraic multigrid preconditioner for the graph Laplacian. The proposed approach uses aggressive coarsening based on the aggregation framework in the setup…
Parallel Unsmoothed Aggregation Algebraic Multigrid Algorithms on GPUs
James Brannick, Yao Chen, Xiaozhe Hu +1
We design and implement a parallel algebraic multigrid method for isotropic graph Laplacian problems on multicore Graphical Processing Units (GPUs). The proposed AMG method is base…
