NON-STOP CALCULATION PROCESSING DEVICE, NON-STOP CALCULATION PROCESSING SYSTEM, NON-STOP CALCULATION PROCESSING METHOD, AND NON-STOP CALCULATION PROCESSING PROGRAM

摘要

PROBLEM TO BE SOLVED: To provide a non-stop calculation processing device in which even when multiple faults occur in a system, a calculation processing result can be repaired so as to cause the calculation processing to continuously be executed.SOLUTION: A non-stop calculation processing device according to the present invention includes: calculation execution means which belongs to any of groups, and stores input data so as to perform calculation processing; storage means for causing calculation execution means, other than the calculation executing means in the same group to which the calculation execution means belongs, to store duplicate data obtained by duplicating input data in association with identification information of the calculation execution means; diagnosis means for diagnosing the calculation execution means so as to detect a fau instruction means for instructing, when a fault of any one of the calculation means is detected, the calculation execution means, which stores duplicate data associated with the calculation execution means, to execute calculation processing using the duplicate data; and output means for substituting an execution result, output by the calculation execution means in which the fault is detected, with an execution result of calculation processing using the duplicate data so as to output it.
