Abstract: (SISSA)

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 \sim 0.064

~fm (

L > 4

fm, and

M_\pi 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.
