Improvement of algorithms for dynamical overlap fermions
Abstract
We investigate the algorithms for dynamical overlap fermions aiming at improving the performance for large-scale simulations. We look for the best combination of Hybrid Monte Carlo options and iterative quark solvers with respect to the numerical costs. Our main target is a Nf=2 simulation with overlap fermion on a 163× 32 lattice at lattice spacing around 0.12 fm.
