Adaptive algebraic multigrid methods have meanwhile established themselves as standardsolvers in lattice QCD computations on current supercomputers. In this paper we review re-cent additions and recent new use cases for the solvers, in particular our DD-αAMG methodand report performance results obtained on JUWELS at JSC..

When solving linear systems with the overlap operator at nonzero chemical potential $μ$ in lattice QCD one needs, at every iteration of the iterative solver, to apply the sign function evaluated on a non-Hermitian operator $Q_μ$ times a vector, i.e., $sign(Q_μ)v$. In this work we describe how deflation and (the more recently proposed) polynomial preconditioning can be applied to this problem, in particular in the context of lattice QCD. [...]
