COMMUNICATING SEQUENTIAL PARALLEL COMPUTING IN-PROCESS MODELING

The dynamic simulation of large systems usually requires considerable time. To achieve better performance parallel machines with increasing capabilities are available. This paper introduces the parallelisation of structural models based on dynamic simulation of chemical systems. The principle of structural modelling is the very fine decomposition o f the systems, followed by the repetitive calculations of the elementa ry changes that occur in given time and spatial intervals. To realise parallelism, CSPROLOG was chosen as,a parallel language. The parallel execution of simulation was performed in two levels: the parallel calc ulation of the elementary changes (for single units), and the parallel calculation of units (for technological plants). The developed method can be applied to systems,from laboratory test tubes to entire chemic al plants.
