基于HDF5文件格式的KYLIN-2软件组件库

摘要

KYLIN-2是中国核动力研究设计院自主研发的先进中子学栅格(组件)计算软件,针对KYLIN-2软件中海量数据存储和处理的问题,提出一种基于对分层数据存储格式v5(HDF5)的计算数据存储方案.首先,对HDF5文件格式进行了研究;其次,根据KYLIN-2软件需求,设计了基于HDF5文件格式的组件库KYMRES;最后,通过自开发的HDF5文件读写工具完成了KYMRES库的实现过程.通过性能测试表明,基于HDF5文件格式的组件库KYMRES较常规存储方案具有更高的I/O效率,其读、写效率平均提升到旧算法的2.3倍和4.5倍.KYMRES库在海量数据存储和处理方面具有显著优越性,为KYLIN-2软件提供了一种新型的数据存储和管理方案.%Nuclear Power Institute of China (NPIC) developed an advanced neutron transport lattice code,namel KYLIN-2.To solve the problem of mass data storage and processing in software,a computing data storage solution based on Hierarchical Data Format v5 (HDF5) was proposed.Firstly,HDF5 file format was researched.Secondly,according to the requirements of KYLIN-2,KYlin-2 Main RESults databank (KYMRES) based on HDF5 was designed.Finally,KYMRES was realized by self-developed HDF5 read/write tool.The performance tests show that KYMRES has a higher I/O efficiency compared with conventional storage solutions,the efficiency of reading and writing is increased to 2.3 and 4.5 times on average that of the old algorithm.KYMRES has significant advantages in mass data storage and processing.and provides a new data storage and management solution for KYLIN-2.
