Optimizing multigrid reduction-in-time (MGRIT) and Parareal coarse-grid operators for linear advection
Hans De Sterck, Robert D. Falgout, Stephanie Friedhoff +2
Parallel-in-time methods, such as multigrid reduction-in-time (MGRIT) and Parareal, provide an attractive option for increasing concurrency when simulating time-dependent PDEs in m…
Provably Optimal Parallel Transport Sweeps on Semi-Structured Grids
Michael P. Adams, Marvin L. Adams, W. Daryl Hawkins +7
We have found provably optimal algorithms for full-domain discrete-ordinate transport sweeps on a class of grids in 2D and 3D Cartesian geometry that are regular at a coarse level…
Parallel Performance of Algebraic Multigrid Domain Decomposition (AMG-DD)
Wayne B. Mitchell, Robert Strzodka, Robert D. Falgout
Algebraic multigrid (AMG) is a widely used scalable solver and preconditioner for large-scale linear systems resulting from the discretization of a wide class of elliptic PDEs. Whi…
