Status and challenges of simulations with dynamical fermions
arXiv:1211.5069
Abstract
An overview over the current state of algorithms for dynamical fermion simulations is given. In particular some insight into the functioning of the determinant spitting techniques is discussed. The critical slowing down of the simulations towards the continuum limit and the role of the boundary conditions is also reviewed.
