Problems solved by technology

However, fleet fault tolerance faces more challenges
First of all, when the scale of the cluster system continues to expand, according to statistical laws, the reliability of the entire system will inevitably decline
Second, the parallelism between cluster nodes makes it more difficult to fully obtain and restore the state of the application
This technology has been proven to be one of the most effective cluster fault tolerance strategies, but this technology does not realize the spatial locality of cluster fault processing, and its overhead is directly related to the system scale

Embodiment Construction

[0101] In order to make the purpose, technical solution and advantages of the present invention clearer, a cluster fault-tolerant system, device and method of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0102] The cluster fault-tolerant system pursues the following goals: 1) Wide adaptability to applications. Cluster fault tolerance should be as independent as possible from applications, parallel application middleware, and not even dependent on the node operating system, so as to facilitate application developers and system managers, that is, the fault tolerance mechanism should be as transparent as possible to applications. 2) Low overhead under conditions of trouble-free operation of the system. The damage caused by the fault tolerance mec...

Abstract

The invention discloses a cluster fault tolerance system, a device and a method. The system includes: a remote checkpoint server which is used to respond the remote checkpoint request from a faulty node and execute the checkpoint operation; a node faulty checking module which is used to monitor the operating system of a local node and the running state of an assigned process and to trigger a remote checkpoint; and a communication system checkpoint module which is used to realize the checkpoint of the communication device and support the recovery function of communication breakpoint. The invention provides localized fast fault restoration for the parallel processing cluster, has a lower overhead and good expansibility, and makes ideal availability for the cluster system with ten billions and hundred billions calculation scale.

Description

technical field [0001] The invention relates to the field of computer parallel processing fault tolerance technology, in particular to a parallel processing cluster fault tolerance system, device and method. Background technique [0002] The application of computer parallel processing technology represented by clusters in modern society has reached considerable breadth and depth. As an important part of the social information infrastructure, the reliability of parallel processing in the cluster system has already had an impact on the economy and society. At present, with the continuous expansion of the cluster system scale and the gradual increase in complexity, the reliability of its parallel processing has shown a downward trend, which has attracted widespread attention from academia and industry. The demand for its engineering application is increasingly urgent. [0003] A cluster is a parallel computer system composed of multiple independent computers (called nodes of ...
