摘　　要：To reduce the overhead of coordinated checkpoint algorithm executing, this paper introduces the concept of ＂computing checkpoint＂ to design an efficient coordinated checkpoint algorithm. Through piggybacking the information that which processes have taken new checkpoint in the broadcast committing message, the checkpoint sequence number of every process can be kept consistent in all processes, so that the unnecessary checkpoints and orphan messages can be avoided in the future running. The algorithm needn＇t block any process and has lower overhead than other proposed coordinated checkpoint algorithms.
