Abstract: A method comprises analyzing multi-threaded process-oriented object code representing a simulation model and transforming said multi-threaded process-oriented object code to event-based object code representing a simulation model equivalent to simulation model represented by said multi-threaded process-oriented object code. Transformation is performed automatically in response to the analysis and includes creating continuation functionality between adjacent threads of execution. Analyzing object code includes determining a potentially blocking method and analyzing its control flow. Transforming multi-threaded process-oriented object code includes configuring the event-based object code to schedule a jump to a first one of a plurality of non-blocking Runnable methods of the simulation model represented by the event-based object code.
