Research in parallel simulation has been around for more than two decades. However, the number of papers reporting on its application to real world problems is limited. At the 2002 PADS conference, researchers discussed the need to go beyond synchronization and performance issues and, in particular, to demonstrate that parallel simulation could be used in real world applications outside military and network simulations. Since then, we have seen an increase in the number of papers on parallel simulation applications in areas such as operations management and the physical sciences. This paper presents a parallel discrete-event demographic simulation tool which has been developed using sik parallel simulation library. A number of experiments have been conducted to evaluate the simulation performance. The result shows that good event parallelism can be achieved.
