|Abstract:|| One of the challenges in a virtual environment stems from the requirement to simultaneously execute the simulations in real-time to support human interaction, in conjunction with maintaining a consistent view of the shared simulated environment (meaning a consistent set of simulation state data). Maintaining a consistent set of simulation state data in the presence of network latency is difficult if individual data items are updated at rates faster than the network can move it. The principle application of DIS-based simulation environments has been in the domain of training where “consistency” is often judged in subjective terms such as the simulation looking and feeling correct. New application areas for these systems are emerging in the analysis and test domains. For these domains, quantifying shared state consistency in terms of overall distributed application architecture is desirable. This research validates the effect that thread rates have with direct measurement on a single work station emulating a real-time distributed system. Latencies due to the software architecture may significantly affect the consistency of the simulation. The results discussed in this paper are helpful to the Air Force community as real-time distributed systems are being used more for the purpose of analysis.
