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…

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…
