摘要
设计一种针对分区操作系统的文件并行访问方法,用于解决分区文件系统面临的文件并行访问问题。针对分区操作系统的文件并行访问方法包括三个步骤:1)采用两种B+树(读管理树和写管理树)分别管理读写分支; 2)事务日志正常提交后用写管理树的指针更新读管理树的指针; 3)分区读写操作执行流程。方法可解决分区文件系统面临的文件并行访问问题。
This paper belongs to the professional filed of computer system software,and involves a parallel file access method for partitioned operating systems.A file parallel access method for partitioned operating systems consists of three steps：steps 1）two kinds of B＋ trees （reader trees and writer trees）are used to manage the reading and writing branches respectively;steps 2）after the transaction log is submitted normally,the pointer to the management tree is updated by using the pointer to the write management tree;steps 3）partitioned read-write operation execution flow.After implementing the parallel file access method designed in this paper,we can solve the parallel file access problem faced by partitioned file systems.
