Discrete Event-Based Simulation of Grid Computing Systems

Grid systems are emerging as new large scale distributed computing paradigm aiming to manage and allocate geographically distributed computing resources such as processing power, memory, storage and networking to applications and users in an efficient and transparent manner. Grid systems, however, are new paradigms as regards their infrastructure, specific software and deployment, making thus their use very difficult and complex for experimental studies of large-scale distributed applications. The simulation of such systems is therefore a de facto approach. Although the simulation field is mature and there are fundamental results for the simulation of distributed computing systems, recent developments in large-scale distributed systems such as Grids, are raising issues not tackled in the simulation of the traditional distributed systems.
