Parallel Programming Models and Languages
并行程序设计模型和语言

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.
