Abstract [en]

We discuss a parallel implementation of an agent-based sim-ulation. Our approach allows to adapt a sequential simulator for large-scale simulation on a cluster of workstations. We target discrete-timesimulation models that capture the behavior of WWW. The real-worldphenomena of emerged aggregated behavior of the Internet populationis studied. The system distributes data among workstations, which al-lows large-scale simulations infeasible on a stand-alone computer. Themodel properties cause traffic between workstations proportional to par-tition sizes. Network latency is hidden by concurrent simulation of mul-tiple users. The system is implemented in Mozart that provides multi-threading, dataflow variables, component-based software development,and network-transparency. Currently we can simulate up to 106 Webusers on 104 Web sites using a cluster of 16 computers, which takes fewseconds per simulation step, and for a problem of the same size, parallelsimulation offers speedups between 11 and 14.
