  We present a next generation of multi-particle Monte Carlo (MC) Event
generators for LHC and ILC for the MSSM, namely the three program packages
Madgraph/MadEvent, WHiZard/O'Mega and Sherpa/Amegic++. The interesting but
difficult phenomenology of supersymmetric models at the upcoming colliders
demands a corresponding complexity and maturity from simulation tools. This
includes multi-particle final states, reducible and irreducible backgrounds,
spin correlations, real emission of photons and gluons, etc., which are
incorporated in the programs presented here. The framework of a model with such
a huge particle content and as complicated as the MSSM makes strenuous tests
and comparison of codes inevitable. Various tests show agreement among the
three different programs; the tables of cross sections produced in these tests
may serve as a future reference for other codes. Furthermore, first MSSM
physics analyses performed with these programs are presented here.
