  A number of promising results of a new 3+1 dimensional Monte Carlo parton
cascade including inelastic multiplication processes (gg <--> ggg) are
elaborated: (1) thermalization and chemical saturation; (2) the onset of
longitudinal hydrodynamical expansion; (3) the build up of elliptic flow. We
first briefly outline the basic idea of the algorithm. Full simulations are
done with initial conditions for the kinetic partons via minijets or with ones
stemming from a color glass condensate. The inclusion of the inelastic channels
leads to a very fast kinetic equilibration and also to an early creation of
pressure.
