摘要： 为了解决并行软件开发复杂及维护困难的问题，提出一种并行软件建模的方法。利用统一建模语言(UML)的扩展机制建立了一系列模型，描述了分布式共享内存的基本程序结构建模，通过组合这些基本模型，创建新的模型来适应具体应用。该建模方法保留了UML易理解、易扩展和易于指导工程实践的特点，便于从串行建模扩展到并行建模。通过对一个并行应用的描述，表明该方法对实际的并行程序设计具有指导意义。

Abstract: This paper proposes a parallel modeling method to improve design decision and reduce time-consuming software development. It describes how to customize a series of models for shared and distributed memory application by using UML extension mechanisms, and how to support real applications by combing these basic models. The method maintains the features of UML such as facilitating understanding, customization, guideline for practical application and extension from sequential modeling to parallel modeling. The usefulness of this method is demonstrated by modeling a real parallel application.
