This paper describes a software enviroment devised to support parallel and sequential discrete-event simulation. It provides assistance to the user in issues such as selection of the synchronization protocol to be used in the execution of the simulation of the model The software framework has been built upon the bulk-synchronous model of parallel computing. The well-defined structure of this model allowed us to predict the running time cost of synchronization protocols in accordance with the particular work-load generated by the execution of the simulation model. We exploit this feature to automatically generate the simulation program.
