The elliptic flow v{sub 2} and the ratio of the shear viscosity over the entropy density, {eta}/s, of gluon matter are calculated from the perturbative QCD (pQCD) based parton cascade Boltzmann approach of multiparton scatterings. For Au+Au collisions at {radical}(s)=200A GeV the gluon plasma generates large v{sub 2} values measured at the BNL Relativistic Heavy Ion Collider. Standard pQCD yields {eta}/s{approx_equal}0.08-0.15 as small as the lower bound found from the anti-de Sitter/conformal field theory conjecture.
