Process Checkpoint Implementation Based on Minix
Li Yi · Jisuanji gongcheng · 2003
When process is in user status, storing the userstack data and kernel context data of a process to the data segment of the process its own,the process context simply is : user register context and user data segment. Statecheck operation of checkpoint preserves the user register context and user data segment of process checkpointed at this time to checkpoint file. Staterestore is opposite to the statecheck. We introduce the user level checkpoint implementation based on minix,and make some optimizing for it in this paper.
