Query: Local bosonic versus HMC --- a CPU cost comparison   We compare the CPU cost of HMC to various implementations of the Hermitean
variant of L\"uscher'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.
