Yang Hui, Hongzhong Chen · 2010
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.
