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…

An adaptive aggregation based domain decomposition multilevel method for the lattice wilson dirac operator: multilevel results
A. Frommer, K. Kahl, S. Krieg +2
In lattice QCD computations a substantial amount of work is spent in solving linear systems arising in Wilson's discretization of the Dirac equations. We show first numerical resul…

Adaptive Aggregation Based Domain Decomposition Multigrid for the Lattice Wilson Dirac Operator
Andreas Frommer, Karsten Kahl, Stefan Krieg +2
In lattice QCD computations a substantial amount of work is spent in solving discretized versions of the Dirac equation. Conventional Krylov solvers show critical slowing down for…
