Abstract: In this paper. a software is described to generate multiple parallel simulationtasks automatically from a kind of modelnystate equations. After the model is inputted,the automatic progress can be realized by the software to generate multiple parallel simulation tasks and then compute them on multiple processors. The tasks generated by thesoftware are ensured to be equitable. This software is suitable for the message--passinghomogeneous MIMD systems to get high speedup of simulation.
