STEFAN SCHEFER University of Zurich: Our ability to simulate QCD on the lattice has improved significantly over the last years. This is mainly due to conceptual advances in the algorithms and our understanding of QCD. I will review the physics ideas behind current lattice simulations. The ongoing CLS simulations with dynamical up, down and strange quarks will serve as an example of what can be currently achieved and where future improvements are needed.
