T ime Warp vs. Chandy-Misra: A worst-case comparison

We address the question of whether one can find a worst-case example simulation model, on which the Time Warp approach to parallel discrete event simulation can arbitrarily outperform the ChandyMisra conservative methods or vice versa. Under our simplifying assumptions, we prove that (1) there exists a p-process simulation model on which Time Warp outperforms Chandy-Misra by a factor of p, and that (2) no opposite example exists; Chandy-Misra can only outperform Time Warp by a constant factor.
