Many Cores and Still Delays: Simulating Multi-Core Communication Software Execution, In Ghassan Beydoun (ed.), Proceedings of The 11th International Conference on Computer Modeling and Simulation (ICCMS 2019).

The effects of software execution are typically ignored in network simulators. This leads to inaccurate simulation results for new and emerging network technologies where packet processing in software has a significant impact on network performance. In this paper we extend our prior work to develop models that capture the temporal aspects of software execution on both uni- and multi-core devices. When executed in parallel with existing network protocol models in network simulators, they significantly improve the accuracy of the simulation results. We demonstrate the applicability of the extended methodology by modeling the execution of communication software on one multi-core device, the Galaxy Nexus smartphone, and evaluate the resulting models in terms of accuracy and scalability. We find that our models are able to reproduce the behavior of the modeled software, and that the models scale well with the number of nodes, cores, and threads included in the simulation; i.e., the simulation overhead increases linearly with the number of nodes.
