摘　　要：Exascale systems have been under development for quite some time and will be available for use in a few years. ]t is time to think about future post-exascale systems. There are many main challenges with regard to future post-exascale systems, such as processor architecture, programming, storage, and interconnect. In this study, we discuss three significant programming challenges for future post-exascale systems： heterogeneity, parallelism, and fault tolerance. Based on our experience of programming on current large-scale systems, we propose several potential solutions for these challenges. Nevertheless, more research efforts are needed to solve these problems.E级高性能计算系统已经研制很长时间,可以在未来几年投入使用。现在是时候考虑未来的后E级高性能计算系统。后E级系统存在许多主要挑战,例如处理器体系结构、编程模型、存储架构和互连网络。讨论了后E级系统编程模型面临的3个重要挑战:异构性、并行性和容错性。基于我们当前在大规模系统上编程的经验,针对这些挑战,提出一些可能的解决方案。然而,未来需要更多研究工作以应对这些挑战。
