Description
I outline the simulation of lattice QCD with $N_f=2+1+1$ optimal domain-wall quarks at the physical point, on the $64^3 \times (6,8,10,12,16,20) $ lattices, for three lattice spacings $a \sim 0.064-0.075$ fm. The quark masses and lattice spacings are determined at the zero temperature on the $64^4$ lattice. The topological susceptibility of each gauge ensemble is measured by the Wilson flow. In this talk, I present the topological susceptibility $\chi_t(a,T) $ of these gauge ensembles for temperature $T \sim 150-520$ MeV, and also obtain $\chi_t(T)$ in the continuum limit.
