We simulate an ultra-relativistic gluon gas in a partonic cascade using the Boltzmann Approach for Multi Parton Scattering (BAMPS) with pQCD-based interactions. Furthermore elastic 2<->2 and inelastic 2<->3 processes with constant cross sections are implemented. The hydrodynamic transport parameter shear viscosity is extracted via two different approaches: first from a relativistic stationary velocity gradient and in a second method from equilibrium fluctuations using a Green-Kubo relation. Both methods are compared to an analytic relation and are used to investigate the alpha_s dependece of the shear viscosity to entropy ratio in a partonic gas at T>T_c.
