Comparison of the mass preconditioned HMC and the DD-HMC algorithm for two-flavour QCD
arXiv:1011.0911
Abstract
Mass preconditioned HMC and DD-HMC are among the most popular algorithms to simulate Wilson fermions. We present a comparison of the performance of the two algorithms for realistic quark masses and lattice sizes. In particular, we use the locally deflated solver of the DD-HMC environment also for the mass preconditioned simulations.
