Abstract

Robustness of the simulation mechanism is a requirement for acceptability of distributed simulation environments. We consider complex and erratic distributed conservative simulations, using colliding pucks as a guiding example. A new mechanism is introduced which allows logical processes to cooperate locally and advance. Advance is made through the collective selection of the next event in a group of logical processes. The algorithm demonstrates scalability through the locality of its determination. A description and proof of correctness is given. The effectiveness of the cooperative acceleration mechanism is illustrated with measurements on road traffic and colliding pucks simulations.
