| Abstract(in English) | Duplex systems consist of two identical computing modules running the same task. Outputs from the two modules are compared with each other to detect faults. When an error is detected, the system cannot identify which module is out of order. Thus, in a conventional duplex system, the system rolls back totally and retries the task when it detects an error. Because the total system rollback involves the both two modules and interrupts processing even in a correctly working module, it may lower system performance. In this paper, we propose two alogorithms which do not use additional modules but utilize time-redundancy-based approach to decrease the performance degradation due to the total rollback. Performance of these algorithms are evaluated through analysis. They show better performance than that of the conventional one. |
