Incorporated with twisted boundary condition, Polyakov loop correlators can give a definition of the renormalized coupling. We employ this scheme for step scaling method (with size s = 2) in search conformal fixed point SU(3) gauge theory 12 massless flavors. Staggered fermion and plaquette action are used lattice simulation six different sizes, L/a 20, 16, 12, 10, 8 6. For largest size, we large number Graphics Processing Units (GPUs) accumulated 3,000,000 trajectories total. found that function sigma (u) is consistent u low-energy region. This means existence point. Some details our analysis simulations will also be presented.
