Efficiencies and optimization of HMC algorithms in pure gauge theory

Abstract: As a prerequisite to dynamical fermion simulations a detailed study of optimal parameters and scaling behavior is conducted for the Schroedinger functional at fixed renormalized coupling. We compare standard hybrid overrelaxation techniques with local and global hybrid Monte Carlo. Our efficiency measure is designed to be directly relevant for the strong coupling constant as used by the ALPHA collaboration.
