基于 HIP 也可以实现 SYCL 统一规范 [38] .

3 总 结
本文基于高性能计算应用软件的现状趋势,对宇宙 N 体模拟、大气与地球系统模式、计算材料相场动力学、
分子动力学、量子计算化学和格点量子色力学等应用开展了并行计算特征分析,提炼了应用的典型算法和软件
的共性问题,并开展了解决的对策讨论.
在国产异构计算高性能计算环境下,由于国产架构不同于主流的体系架构,其算法实现和软件设计有很大
差异.另外我国自主的硬件体系架构设计起步较晚,所构建的软件生态环境包括系统工具和程序调试工具等等
还远不成熟,给应用程序开发团队开发程序增加了现实难度.为了有效开展基于国产高性能异构计算算法和软
件设计,现给出两点发展建议:
(1) 尽快建立我国高性能计算的统一软硬件标准.可从指令集、API 接口、软件架构、网格环境对接等方
面建立统一规范.
(2) 兼容已有国际主流标准并积极参与国际规范标准的制定,提高国产超级计算平台与开源软件的兼容性.
