The ROme OpTimistic Simulator: A Tutorial

In this tutorial we present the ROme OpTimistic Simulator (ROOT-Sim), a general-purpose Parallel Discrete Event simulation platform built according to the optimistic synchronization scheme, which allows-via the adoption of a simple/reduced API-to implement simulation models via event handlers relying on standard ANSI-C. We present the set of paradigms which ROOT-Sim is built on, and its internal design, along with the offered facilities. We also explain the simulation-model programming paradigm, and give an example of a basic simulation model, which stands as a building block for more complex ones
