Abstract

The present invention relates to a design method of a flexible scheduling multi-redundant computer system, comprising: a monitoring module, the monitoring module is arranged between a CPU board and a network switching board, which allocates and schedules the data sent by the network switching board to the CPU board task, monitoring the working state of the CPU board; when the CPU board is faulty, the task is switched to another CPU board; the faulty CPU board is reset; a method of multi-redundant computer that realizes flexible scheduling according to the present invention, through the monitoring module Realize flexible scheduling for the CPU boards in the system. While switching the CPU boards for faulty tasks, reset the faulty CPU boards in time to reduce the occupation of the CPU boards and keep the CPU boards in the system in a normal state at all times, which effectively guarantees the system tasks. Reliability reduces the number of redundant boards, and the system structure is simple, which is convenient for stocking and maintenance, and the system cost is low.

Description

technical field [0001] The invention relates to a design method of a multi-redundant computer system with flexible scheduling. Through flexible scheduling of multiple CPU board resources in the system, the switching of any faulty CPU board is realized, while ensuring the reliability of system tasks, significantly reducing Number of redundant CPU boards. Background technique [0002] In the occasions requiring high reliability, multi-redundant computer systems are mostly used to increase the task reliability of the system. Most of the multi-redundant computer systems currently used in the industry are dual-redundant or triple-two voting systems. Among them, the number of working CPU resources and redundant CPU resources should be configured according to 1:1 or 1:2. The number of redundant resources is large. Due to the fixed replacement relationship, a certain CPU board can only be replaced by its backup board, which is not flexible. . Contents of the invention [0003] ...
