520 _ _ |a Addressing certain materials science problems, e.g. inhomogeneous materials, using Density Functional Theory will require exascale compute capabilities as a sufficiently large number of atoms need to be simulated. In this chapter we consider a particular approach and an implementation that is optimized for extreme scale parallelism. We provide an overview on the Kohn-Sham approach as well as its application areas and discuss in detail the application KKRnano. Here we focus on recent efforts to port this application to GPU-accelerated architectures.
