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.
