Enabling OMNeT++-based Simulations on Grid Systems

Simulations are typically computationally intensive problems, and lend themselves for execution on large-scale PC clusters or grids. Using grid infrastructure for discrete event simulation is currently not prevalent, but making grid technology easily accessible to simulation users can change that picture significantly. In this paper we give a detailed overview how the OMNeT++ simulation framework was ported onto a gLite-based grid infrastructure. The porting of the simulation framework to the grid infrastructure was supported by the GASUC Team of the EGEE III project. Later on in the paper we show an example grid service which is able to execute queuing network simulations, and assess its performance on the grid.
