Abstract

The invention relates to a multi-controller calculation redundant cluster based on a Loongson processor, which comprises a plurality of controllers, a switch and a shared storage space. Slave controllers monitor all master controllers to back up working contents and states of the master controllers in real time; the controllers send out heartbeat messages, acquire the heartbeat messages of other controllers and judge the working states of other controllers; when a failure controller is the master controller, other non-failure controllers identify the master controller as a fault, and the controller with the highest priority in other non-failure controllers is switched into the master controller; if the failure controller is the slave controller, the failure controller is identified as thefault; and according to actual demands, the numbers of hosts and standbys are determined. The multi-controller calculation redundant cluster disclosed by the invention has a hot standby function at the system level; when a main computer has a fault, a service can be automatically migrated to a backup computer, and the backup computer monitors a working state of the main computer in real time, so that real-time performance of switching is ensured, and data loss is reduced.

Description

technical field

[0001] The invention relates to a multi-controller computing redundant cluster based on a Godson processor, which belongs to the field of ground equipment reliability design. Background technique

[0002] As domestic Loongson processors are more and more widely used in the aerospace industry, higher and higher requirements are put forward for the reliability of domestic Loongson processor electrical equipment. Only by improving the reliability of a single machine can not meet the reliability requirements of some systems, so how to improve the reliability of the system has become a hot topic in reliability research.

[0003] Redundancy technology is one of the most effective methods to improve the reliability of the control system. Generally speaking, there are two types of management modes for redundant services: one is to adopt a global centralized management mode, and the system has a global unique manager, which is responsible for system resource allocati...
