A System for Aggregated Visualization of Multiple Parallel Discrete Event Simulations

In this paper we present a system for the simultaneous visualization of several parallel executed simulation replications. By aggregating the scenes of multiple similar simulations into one single scene it is possible to make a visual statistical analysis of a set of discrete event simulations as well as to easily compare different system parameterizations. The aim of our system is to enhance the model analysis, verification and validation process in terms of speed and ease. The parallel execution of several simulations of complex models and the visualization of these cannot be done on one computer, thus a parallel approach is necessary. Our system uses a thin-client and multiple processors on a PC-cluster. The rendering and the simulation execution are done on processors of the cluster. The client is used only for the visualization of the images transmitted by the cluster and for user interaction.
