In the first part of this talk we will present and discussnumerical results for a set of multilevel methods forpreconditioning all-at-once space-time finite elementdiscretizations. In particular we are interested in therobustness with respect to uniform mesh refinement, as well asscalability in a massively parallel setting.In the second part, we present new results regardingadaptive space-time finite element methods on structureddecompositions, using anisotropic refinement strategies,applied to a space-time extension of Kellogg's problem.
