摘要
In this paper, a quasi-synchronous approach for checkpointing / recover is proposed. It uses a new concept of forced checkpoint. It helps in ensuring a small re-execution time after recovery from a failure. The approach offers a very simple recovery scheme, comparable to that in synchronous approach, even though achieving synchronization among the processes is not required unlike in synchronous approach.
