摘　　要：在大规模并行系统上,并行应用涉及的文件操作的可靠性和文件数据的完整性验证很重要。基于传统串行MD5摘要的文件验证手段无法满足大规模并行应用的需求,提出一种多层MD5并行摘要思想。基于此实现了文件完整性实时检测接口,并测试了串行MD5摘要和多层MD5摘要的性能,以及相应的文件完整性检测技术的性能。The reliability of file operations and the integrity verification of file data the parallel applications involving in massively parallel systems are very important. The file verification means based on traditional serial MD5-message digest cannct meet the demand of massively parallel applications. In this paper we present a multi-level MD5-message parallel digest idea, and implement the real-time file integrity detection interface based on it, and test the performances of serial MDS-message parallel digest and multi-level MD5-message parallel digest, as well as the performance of the related file integrity detection technique.
