PROBLEM TO BE SOLVED: To provide a check point acquisition timing decision method for substantially improving the efficiency of a communication processing generated mutually between fault tolerant computers. SOLUTION: A computer (A) is provided with a step (step A2) for informing the computer (B) of its own check point acquisition time and the computer (B) is provided with the step (step B1) for receiving the check point acquisition time of the computer (A) informed by the computer (A) and the step (step B2) for deciding its own check point acquisition time based on the received check point acquisition time of the computer (A). Thus, since the acquisition time of the check point of both can be slid with an appropriate time width, the efficiency of the communication processing generated mutually between the computers is substantially improved. |
