Abstract: Using the new supercomputer JUMP at the Research Center Jülich, we were able to simulate large lattices (up to L=2·106, meaning a new world record) for long times (up to t=6000 for L=1.5·105). Using this data, we examined the dynamical critical exponent z. The old assumption of z=2 with logarithmic corrections seems very unlikely according to our data, leaving the asymptotic value of z ~= 2.167.
