Connecting together multiple computers to
solve a single real-time problem is certainly a very challenging
engineering task. An aircraft simulator is an example of one of the
most demanding of these real-time applications. This paper
addresses some of the unique requirements of distributed computing
architectures for simulators, and it summarizes the two major
approaches which have been used to date. The concept of a new
approach—shared-memory networking—is introduced and
compared to the traditional approaches.
