介绍了顺序和并行离散事件仿真的主要算法。使用基于转发器的多计算机对一组不同的模拟器进行了评估和比较：顺序、并行保守和并行乐观。对于所提出的模型，保守模拟器显示出更好的加速。得到的结果表明，使用并行系统可以显著改善执行时间，但前提是所仿真的模型具有粗粒度和高度自同步等特性
The main algorithms for sequential and parallel discrete event simulations are introduced. A set of different simulators is evaluated and compared using a transputer-based multicomputer: sequential, parallel conservative and parallel optimistic. For the proposed model, the conservative simulator shows better speedups. The obtained results show that a significant improvement on execution time can be obtained using parallel systems, but only if the model under simulation have some properties like coarse grain size and high degree of self-synchronisation.<<ETX>>
