In defense of discrete-event simulation

In the October 1991 issue of TOMACS, Bagrodia, Chandy, and Liao present “A Unifying Framework for Distributed Simulation.” The paper is a well-conceived, well-written contribution to the literature. However, I wish to call attention to one paragraph and discuss its implications; my object being to stimulate a discussion within the parallel discrete-event simulation community concerning the relationship between discrete-event simulation and parallel discrete-event simulation. The authors write:
