SWENDSEN-WANG DYNAMICS ON LARGE 2D CRITICAL ISING MODELS

Lattices up to size 6400*6400 are simulated on a 32-processor Intel Hypercube parallel computer. At the critical temperature of the square-lattice Ising model, the magnetization decays roughly exponentially with time if we start with all spins parallel and if the lattice is large enough. This result is consistent with those of Heermann and Burkitt.
