并行计算技术的发展已有20多年的历史了.时至今日,高性能并行计算仍然缺乏有效的并行程序设计方法和工具,使得编写并行程序、理解并行程序的行为、调试和优化并行程序的性能都很困难.从分析并行程序设计困难的原因入手,指出了当前各种高性能并行机系统支持的并行程序设计方法存在的诸多问题,综述了并行程序设计模型和语言的研究现状,给出了并行程序设计模型的评价标准,并提出了这一研究领域所面临的挑战性问题,指出了一些未来可能的发展方向.

Parallel computing is about 20 years old. Till now, there is a lack of effective parallel programming methods and tools in high performance computing as a result that it is very difficulty to parallel programming, understanding behaviors of parallel program, debugging parallel codes and optimizing performance. In this paper, the reasons why so difficulty parallel programming is are analyzed, while the issues about parallel programming methods existing in recent high performance parallel machines are addressed,the current status of parallel programming models and languages are surveeyed,the view of the criteria is offered to evaluate parallel programming models,the challenge problems in this area are brought forward,and some future research directions are pointed out.
