摘要：
We present a generalized self-scattering method for generating carrier free flight times in Monte Carlo simulation. Compared to traditional approaches, the added flexibility of this approach results in fewer fictitious scatterings, which is especially appealing for load balance and efficiency when a SIMD parallel computer is used. Speedups from 19% to 69% over an optimized variable-Gamma approach are shown for an implementation on the Connection Machine CM-2. The performance sensitivities to applied fields and grid spacings are also presented. The conversion of existing variable-Gamma software to this new approach requires only a few changes.
