- The paper demonstrates that it is possible to write additive preconditioners such that they have single touch semantics, i.e. load each piece of data only once, work for dynamically adaptive meshes, and can solve d>3-dimensional problems. This allows to study the break-up of molecules of a complexity that was not able before. All steps clearly laid out, formalised and correctness proofs provided. It thus paves the way to a series of multigrid papers from the group which significantly advance the field of matrix-free, single-touch additive, desynchronised solvers.
