Analyzing distributed simulation

Simulation is an important tool in planning. Large simulations require a lot of memory and processing time. In many cases the long simulation times reduce the usability of simulation. In this paper, aspects affecting distributed simulation have been studied, including hardware, software and network related issues. Experiments have been carried out with a distributed simulator, Diworse. Simulation experiments are conducted to show the importance of the used network parameters and the importance of consideration of the used operating system. The achieved results indicate that distributed simulation can be an effective method for reducing the simulation time. Introduction Simulation has become an important modeling tool in many areas. It has been used efficiently in meteorology, telecommunications, physics, etc. Unfortunately, the simulation models are getting larger and, as the result, the time required by the simulation is growing. Multiprocessor computers and distributed processing environments have successfully been used to reduce the growing simulation time 4 . In this paper distributed simulation in a workstation environment has been studied. Special emphasis has been focused on finding the elements that affect to the distributed simulation, and the effects of each element. Network User software
