在BLCR系统的基础上实现一种支持进程打开文件迁移的检查点机制,给出该机制的总体框架、关键技术、进程打开文件保存恢复、状态保存和恢复的流程.实验结果表明,该机制支持多线程、信号、进程打开文件及管道等的保存与恢复,无需重编译内核,对用户具有良好的透明性.

Based on BLCR system,the paper improves and implements a Checkpoint mechanism which supports process opening file migration.It gives its general framework of the system,key technology,file migration supporting and the specific workflow of state checkpoint and state recovery.Experimental results show that the mechanism supports the checkpoint of multiple threads,signal,pipe and process opening file,does not need recompile the kernel,and has better transparency to users.
