Abstract
Based on performance data of the SESAM/T chi L hybrid Monte Carlo simulatio ns at lattice spacing a = 0.079 fm, we prognosticate the computer time need ed for producing full QCD vacuum configurations with N-f = 2 Wilson fermion s, going deeper towards the chiral limit on correspondingly increasing latt ice sizes. In doing so particular attention is paid to autocorrelation effe cts and scaling of iterative solvers within HMC.
