ABSTRACT:
The present invention provides a computer system with an interruption resistance which construction costs are greatly reduced by eliminating lock-run-out sequence when restarting is performed. In a computer system with an interruption resistance, comprising a check point restart function, special process for taking check points are respectively provided for processors included in the computer system. When taking a check point, the special process for taking check points is brought into an ready state by a wake-up portion. After the special process for taking check points takes a check point, the special process for taking check points is brought into a sleep state again. In this manner, check points are not taken when executing an arbitrary process, and therefore, lock-run-out can be eliminated when restarting is performed.
