基于工作流模型驱动的并行算法设计教学方法

《并行算法设计》属于高等计算机程序设计的主要课程之一，其主要难点集中在如何将特定的并行求解模型转化为具体的程序设计语言。传统的教学方法主要通过讲授并行程序设计语言来实现教学目标，已有的教学实践经验里示谊方法存在的诸多不足之处。对此。本文提出了一种基于模型驱动的教学方法，其核心思想是：以并行问题求解模型为教学主线，通过分析与讲授并行问题求解模型的基本特征以及不同模型之问的异同来向学生传授并行算法的关键思想和技巧。最方法的主要优点是：实现了算法设计思想与吴体程序语言的独立性。能有效地引导学生掌握并行问题求解的关键思想和技巧，激发了学生利用简单模型来求解复杂问题的兴趣。

A Teaching Approach to Parallel Algorithm Design based on Workflow Model

Parallel algorithm design is one of the major courses in computer science.The challenging issue of teaching this course is how to translating the solution models into specific programming language.Classical teaching approaches mainly focus on teaching parallel programming language, which has several shortcomings based on existing experiences.In this paper,a workflow model based teaching approach is proposed, which takes efforts into analyzing the parallel problem model and the differences between various models.In this way,the students can obtain the key ideology of parallel algorithm designing and corresponding techniques.In addition, the proposed teaching approach is aiming to making the algorithm designing independent of any programming language,which is of significant importance to inspire students solving complex parallel problems by simple models step by step.
