In this study, the computational performance of the Finite-volume Atmospheric Model of the IAP/LASG （FAMIL） was comprehensively evaluated on Tianhe-2, which was the world＇s top-ranked supercomputer from June 2013 to May 2016. The standardized Atmospheric Model Inter-comparison Project （AMIP） type of experiment was carried out that focused on the computational performance of each node as well as the simulation year per day （SYPD）, the running cost speedup, and the scalability of the FAMIL. The results indicated that （1） based on five indexes （CPU usage, percentage of CPU kernel mode that occupies CPU time and of message passing waiting time （CPU SW）, code vectorization （VEC）, average of Gflops （Gflops_ AVE）, and peak of Gflops （Gflops_PK））, FAMIL shows excellent computational performance on every Tianhe-2 computing node; （2） considering SYPD and the cost speedup of FAMIL systematically, the optimal Message Passing Interface （MPI） numbers of processors （MNPs） choice appears when FAMIL use 384 and 1536 MNPs for C96 （100 km） and C384 （25 km）, respectively; and （3） FAMIL shows positive scalability with increased threads to drive the model. Considering the fast network speed and acceleration card in the MIC architecture on Tianhe-2, there is still significant room to improve the computational performance of FAMIL.展开更多

A series of three- model-day simulations were carried out with standard Aqua Planet Experiment （APE） designed within FAMIL to obtain the time stamp for the calculation of model speed, simulation cost, and model 1/O efficiency. The results of the simulation demonstrate that FAMIL has remarkable scalability below 3456 and 6144 cores, and the lowest simulation costs are 1536 and 3456 cores for 12.5 km and 6.25 krn resolutions, respectively. Furthermore, FAMIL has excellent I/O scalability and an efficiency of more than 80% on 6 I/Os and more than 99% on 1536 I/Os.展开更多

The actual inheritance of the famille rose decoration and color enamel craftsmanship as China＇s ＂intangible cultural heritage＂ is restricted not only by historical change and geographical conditions and also by how to inherit the craftsmanship. In this paper, through the literature studies, sociology investigation, market research, and comparative analysis of the traditional pastel industry in Jingdezhen, the making flows of famille rose decoration and color enamel are introduced plus the author＇s understanding of famille rose decoration and color enamel, and also the understanding and inheritance of Jingdezhen traditional famille rose decoration and color enamel craftsmanship as ＂intangible cultural heritage＂ are discussed. Therefore, theoretical basis and practice guidance are provided for famille rose decoration and color enamel craftsmanship to develop toward the cultural industry, and also a reference in theory and practice is available for the inheritance and development of the handmade ceramic products as ＂intangible cultural heritage＂.展开更多
