X:E级系统结点内编程模型研究

X:intra-node programming models for exascale systems

基于对E级系统特征的分析和对混合编程模型编程经验的总结,提出了对E级系统结点内编程模型的七项需求.对照七项需求分析了现有编程模型的优点和不足.分析可知:对E级系统的结点内编程模型的研究应该在保证编程模型简单性的前提下,有针对性地解决当前编程模型在性能可扩展性、模型层次性和模型异构性的不足.

Based on the summation of the features of exascale systems and past experiences of hybrid programming,7requirements were proposed to support intra-node programming.In comparison to 7 requirements,the existing programming models were analyzed,and their advantage and vulnerability were pointed out.In conclusion,the intra-node programming models for exascale systems should maintain the simplicity as much as possible,and then solve the problems of performance scalability, efficiently utilizing the multi-level memory space,and supporting programming heterogeneous systems.
