Abstract

The invention discloses a status consistent maintaining method applicable to a distributed task management system. The method comprises the following steps: 1) maintaining the node statuses of the distributed task management system; 2) initializing the task of the distributed task management system; 3) changing the task status of the distributed task management system; and 4) dealing with the node faults and recovery. The status consistent maintaining method applicable to the distributed task management system provided by the invention is high in degree of automation, high in reliability, high in robustness, high in communication efficiency, small in occupied bandwidth, good in transportability and simple in task deployment, thereby having a good application prospect.

Description

technical field [0001] The invention relates to a state consistency maintenance method suitable for a distributed task management system, belonging to the technical field of distributed processing. Background technique [0002] In a distributed processing system, each node processes a subset of global tasks, but generally requires collaborative work and state synchronization. After all nodes are processed, the results are summarized, and then the next round of processing is performed. The system may change at any time during operation. The running status of tasks, such as the need to add some tasks to certain nodes, the need to adjust task load balancing, or the failure of a task on a certain node, etc., each node in the system must accurately and timely know the existence and operation of other nodes Otherwise, task omission, task duplication, and task delay may occur. Therefore, how to ensure the consistency of the distributed task system's operating status in the global s...
