Using 10-16 units of Nvidia DGX-1, we have generated the first gauge ensemble for N f = 2 + 1 + 1 lattice QCD with physical (u/d, s, c) domain-wall quarks, on the 64 4 lattice with lattice spacing a ∼ 0.064 fm (L > 4 fm, and M π L > 3). The salient feature of this gauge ensemble is that the chiral symmetry is preserved to a high precision and all topological sectors are sampled ergodically. In this paper, we present the first results of the topological susceptibility and the ground-state hadron mass spectra.
