When a check point function of acquiring a memory image is called in processing of a process 100, a scheduler control part 170 in a check point function part 120 causes a scheduler function part 150 of a system to stop a process schedule, and a process relationship data acquisition part 160 refers to data 140 to acquire a relationship of inter-process communication and informs a memory image acquisition function part 130 of the acquired relationship of inter-process communication.
