The Comparison of Checkpoint Technology in the Cloud
In this paper, the authors assessed 10 kinds of current domestic and foreign popular checkpoint algorithms. It introduced the checkpoint technology and the single process (condor) and distributed the checkpoint algorithms. The distributed checkpoint algorithms were subdivided into synchronous checkpoint algorithms (i.e., CL, SNS) and asynchronous checkpoint algorithms for comparison. They proposed a checkpoint algorithm improvement strategy. Based on the decrease in checkpoint preservation of information, they introduced the assessment of incremental, user participation and compiler-aided algorithms.
