> 中文摘要: 面向数万核大规模计算,JASMIN 框架在使能技术和数值算法上进行了发展和完善,推出了新版本.新版JASMIN 框架保持编程接口兼容,无需用户修改程序,可直接提升已有程序的并行可扩展能力.为考察应用程序在JASMIN 框架支撑下的并行可扩展能力,在天河一号A 超级计算机的数万核上测试和分析了5 个复杂应用程序的并行性能.这些程序是激光聚变、材料科学、高功率微波研究中最具典型代表性的高性能计算需求.结果表明,4 个应用程序可扩展到42000 核,并行效率均在60%以上;3 个应用程序可进一步扩展到84000 核,并行效率均在45%以上.
Abstract:Oriented to the large-scale computation on tens of thousands cores, the parallel software infrastructure named JASMIN has released a new version which has improved the enabling techniques and numerical algorithms. With downward compatible programming interfaces, the new version can enhance the scalability of the programs free of application users’ effort. To investigate the scalability of the programs based on JASMIN, we test and analyze the performance of five complex application programs on tens of thousands cores of TH-1A supercomputer. These programs were developed for the high-performance computation arising from inertial confinement fusion, material science as well as the high-power microwave. It is shown that four programs achieve a parallel efficiency of over 60% on 42,000 cores and three ones achieve a parallel efficiency of over 45% on 84,000 cores.
