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…
Space Decompositions and Solvers for Discontinuous Galerkin Methods
Blanca Ayuso de Dios, Ludmil Zikatanov
We present a brief overview of the different domain and space decomposition techniques that enter in developing and analyzing solvers for discontinuous Galerkin methods. Emphasis i…
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…
