摘要：

We present results of large scale simulations on the Connection Machine (CM) on the scaling behavior of the Zhang model and its variants for the kinetics of self-affine interfaces with power-law noise. Details on implementing this problem on a massively parallel computer such as the CM are given. Our calculations for the case when the amplitude eta of the noise has a distribution P(eta) similar to eta(-1-mu) are in good agreement with earlier findings of non-universality for mu < 7. We present data which suggest that for is mu >= 7 the model is in the universality class of Gaussian noise.
