- Abstract
- To improve the performance of geographically distributed cosimulation, we propose a concept called hierarchically grouped message. The concept improves cosimulation performance, preserving the cosimulation accuracy, by hierarchically grouping messages transferred between simulators in a short period of simulated time into a single physical message, thereby reducing the number of physical messages. Applying the concept to hybrid and optimistic cosimulation, we can reduce the number of rollbacks as well as the communication overhead accompanying the message transfer. Experimental results show the efficiency of the proposed method for practical examples in an internationally distributed cosimulation environment.
