摘要：

We compare the CPU cost of HMC to various implementations of the Hermitean variant of Luscher's local bosonic algorithm (LBA) for 2D massive QED with two flavours of Wilson fermions, We carefully scan a 3-dimensional parameter subspace and find flat behaviour around the optimum. The gain factor of the LBA, as compared to HMC, is slightly smaller for the Re-weighting method than for the Metropolis variants and estimated to about 3.3 for the plaquette and 1.9 for the the meson correlator.
