distributed virtual environments
- Distributed Interactive Simulation (DIS)
- multiplayer video games
- not suitable for analytic simulations of networks: do not guarantee reproduction of temporal relationships in the simulation model
DoD High Level Architecture (HLA)
- spans all M&S in U.S. DoD: training, test & evaluation, analysis
- some aspects directly applicable (e.g., time management)
Parallel discrete event simulation algorithms
- conservative
- always processes events in time stamp order
- null messages, distance between processes, deadlock detection
- optimistic
- detect out of order event processing, roll back to recover
- Time Warp, numerous techniques controlling optimistic execution
- combined protocols (Arvind, Ayani, Bagrodia ...)
