Abstract: We present Monte Carlo simulation results for the dynamical critical exponentzof the two- and three-dimensional kinetic Ising model. Thez-values were calculated from the magnetization relaxation from an ordered state into the equilibrium state atTcfor very large systems with up to(169984)2and(3072)3spins. To our knowledge, these are the largest Ising-systems simulated todate. We also report the successful simulation of very large lattices on a massively parallel MIMD computer with high speedups of approximately 1000 and an efficiency of about 0.93.
