The growing complexity of systems; together with increasing available parallelism provided by multi-core chips; calls for the parallelization of simulation. Simulation speed-ups are expected from co-simulation and parallelization based on models splitting into loosely coupled sub-systems in the framework of Functional Mockup Interface (FMI). However; slackened synchronization between the sub-models and associated solvers running in parallel introduces integration errors; which must be kept inside predefined bounds. In this paper; context-based extrapolation is investigated to improve the trade-off between integration speed-ups; needing large communication steps; and simulation precision; needing frequent updates for the models inputs. An internal combustion engine; based on FMI for model exchange; is used to assess the parallelization methodology.

Keywords: FMI; parallel simulation; signal processing; polynomial extrapolation; real-time; contextbased decision
