Description
Critical slowing down in the fermion sector is a leading obstacle facing the approach to the continuum in lattice gauge theory simulations. Adaptive multigrid ($\alpha$-MG) methods offer a solution to the resulting superlinear growth in the cost of iterative Krylov solves. Ongoing research has suggested that previously developed $\alpha$-MG methods, such as the successful formulation for Wilson-clover fermions, cannot be applied in a black-box fashion to other discretizations. In this talk I will expand on subtle issues offered by the staggered discretization. I will also discuss novel approaches that may sidestep these issues.
