Compelling evidence has recently emerged from lattice simulations in favor of the massive solution of the Schwinger-Dyson equations of Landau-gauge QCD. The main objections to these lattice results are based on possible Gribov-copy effects. We recently installed at IFSC-USP a new GPU cluster dedicated to the study of Green’s functions. We present here our point of view on the Saga and the status of our project. We also show data for the 2D case on a 2560^2 lattice.
