Abstract
An independent checkpointing method using a memory checkpoint on a distributed system that includes a message transmission routine, a message processing routine, and a periodical checkpoint routine. The message transmission routine adds a self checkpoint number to a message to be transmitted when a current process tries to send a message to another process. The message processing routine performs a memory checkpoint and processes a message in reference to a checkpoint number of a transmission process, a checkpoint number of the current process, a memory checkpoint flag, and a message transmission flag when a message is received from a process. The periodical checkpoint routine performs a checkpoint that records a necessary state information for recovery against faults periodically in reference to the memory checkpoint flag.
