The simulation is carried out on the L3 × T = 643 × 64 lattice with lattice spacing a ? 0.064 fm (L > 4 fm, and MπL > 3), using the Nvidia DGX-1 (8 V100 GPUs interconnected by the NVLink). To attain the maximal chiral symmetry for a finite extent (Ns = 16) in the fifth dimension, we use the optimal domain-wall fermion for the quark action, together with the exact one-flavor action for domain-wall fermion. We outline the salient features of our simulation (without topology freezing, and small residual masses), together with the preliminary result of the masses of π±, K±, and D±. ?
