MODULES AND SOLVERS
Friday, 04 July, 09:30
Abstract: Krylov subspace solvers come in a myriad of slightly different flavours. Rather than treat each algorithm as a black box, we have attempted to write a toolbox of self-contained pieces from which the algorithms can be created. This will hopefully make it easier to prototype new methods and/or to easily add useful algorithmic pieces to certain methods. This talk will cover the design, implementation and efficiency concerns of the framework.

IMPROVED STAGGERED FERMIONS
Friday, 04 July, 11:00
Abstract: We examine several variants of improved staggered fermions. We discuss how to construct meson operators. In order to show the improvement on the taste-symmetry breaking interactions, we compute the pion spectrum.

COMPUTATIONAL TECHNIQUES FOR LATTICE PERTURBATION THEORY
Friday, 04 July, 11:45
Abstract: I discuss the need for automated techniques for lattice perturbation theory, and a particular method for carrying this out. I present an implementation of this. Perturbative calculations of the anisotropy and of the heavy quark propagator renormalisation in NRQCD will be used to illustrate the technique.
