We determine the nonperturbative anisotropic parameter of the gauge action in the quenched approximation with less than 1 0x1.dfa38p-891ccuracy using the Sommer scale measured by the Lüscher-Weisz algorithm or smearing tech- nique. We also study the nonperturbative O(a)-improvement of the quark action. The bare quark anisotropy is determined using the masses from the temporal and spatial directions. For the determination of the O(a) improvement coefficients, we apply the Schrödinger functional method.
