Improvements of Lüscher's local bosonic fermion algorithm

Abstract

We discuss the application of hybrid over-relaxation, even-odd preconditioning and a modified local updating procedure to the local bosonic fermion algorithm. Studies on autocorrelation times and the tuning of the parameters of the algorithm are done on various lattice sizes simulating SU(2)-LGT with 2 flavours of Wilson quarks. A substantial decrease of the computational cost could be achieved.
