Abstract

Embodiments of the present invention provide a computer fault-tolerant system and method. In one embodiment, the computer fault-tolerant system comprises: a plurality of fault-tolerant units, wherein each of the fault-tolerant units is communicatively connected with at least one adjacent fault-tolerant unit to form an automatic fault-tolerant network. The fault-tolerance unit comprises: a task distributor and an error sensor. The error sensor of each fault-tolerance unit is configured to monitor in real time whether a working state of the fault-tolerance unit is normal; when an abnormal working state of any fault-tolerance unit is detected, the task distributor transmits the broadcast to search available free fault-tolerant units; and when receiving a response to the broadcast from at least one free fault-tolerant unit, the task distributor selects one of the free fault-tolerant units and assigns the tasks of the fault-tolerant unit in an abnormal working state to the selected one of the free fault-tolerance units.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a computer fault-tolerant system and method. Background technique [0002] In a computer, it can generally be divided into modules such as CPU, memory, and I / O, so fault detection and processing can be realized through redundancy on these modules. By using the same redundant hardware to process the same instruction, supplemented by supporting software fault tolerance, the stability of the continuous operation of the system is greatly improved. [0003] Use the same, redundant hardware components to process the same instructions, and use software to use hot swap, memory mirroring, load balancing, multi-point termination failure, multi-channel I / O, etc., which greatly enhances the stability of the continuous operation of the system . The most widely used method is to use a dual-redundancy or multi-redundancy system to realize system backup, recovery and uninterrupted op...
