Adaptive aggregation-based domain decomposition multigrid for twisted mass fermions
Alexandrou, Constantia; Bacchio, S.; Finkenrath, J.; Frommer, A.; Kahl, K.; Rottmann, M. (2016)The adaptive aggregation-base domain decomposition multigrid method [A. Frommer, SIAM J. Sci. Comput. 36, A1581 (2014)] is extended for two degenerate flavors of twisted mass fermions. By fine-tuning the parameters we ...

DDalphaAMG for twisted mass fermions
Bacchio, S.; Alexandrou, Constantia; Finkenrath, J.; Frommer, A.; Kahl, K.; Rottmann, M. (Proceedings of Science (PoS), 2016)We present the Adaptive Aggregation-based Domain Decomposition Multigrid method extended to the twisted mass fermion discretization action. We show comparisons of results as a function of tuning the parameters that enter ...
