• 中文摘要： 本文中,使用Transputer系統、逐板及降階之蒸餾動態模式兩者皆平行化後,我們獲得"Amdahl's Law"效益在90%以上。我們也發現雖然在平行化過程中,對於processor間之數據傳送必須花費不少力氣,但平行效益事實上只和如何分割各板之計算有關。更進一步的,我們發現雖然降階模式程式更複雜,更平行化效益更高,於是降階模式在平行化之後其基本效益仍可維持。
• 英文摘要： In this study, both tray-by-tray and reduced order dynamic simulation models for distillation columns were paralleled using a Transputer system. Amdahl's law efficiency of more than 90% were obtained using the suggested parallel algorithms. It was also found that although considerable effort must be made to take care of communication needs in the development of parallel algorithm, actual speedup and Amdahl's law efficiency are affected mainly by the even partition of computation load. Moreover, it was found that a high degree of parallelism could be obtained for the reduced order method, despite greater programming effort. Therefore, the advantages offered by the reduced order method could be retained even when implemented on a parallel computing machine.
