A task processing method and device for a cluster system

Abstract

One embodiment of the invention provides a task processing method and device for a cluster system. The method comprises following steps: according to identification information of a current management node that is stored, whether it is the management node of the cluster system itself is determined; if it is the management node, querying a task table stored in a cluster subsystem according to address information of the pre-built cluster subsystem in the cluster system; Identifying status information in the task table as pending status, and executing the task to be allocated whose node identification information is empty, adding identification information of node for processing the task to be assigned to the execution node identification information corresponding to each task to be assigned; otherwise, according to the address information of the cluster subsystem, querying the task table, recognizing the state information in the task table as pending processing state, and performing a target task in which the node identification information is self-identification information, processing the target task. The embodiment of the invention can improve the success rate of task processing of cluster systems.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a task processing method and device for a cluster system. Background technique [0002] A cluster system is a group of independent computers interconnected through a high-speed network, which form a group and are managed as a single system. Each computer in the cluster system may be referred to as each node, each node is independent of each other, and any node can process the tasks received by the cluster system. [0003] When a user communicates with the cluster system, the cluster system appears as an independent computer. Specifically, the cluster system can provide an interface for communicating with the outside to receive tasks, and the interface can forward the received tasks to nodes inside the cluster for processing. Task processing is the core technology in the cluster system. To ensure the normal operation of a cluster system, it is necessary to ensure that each tas...

[0005] However, in the above method, the task pool and resource scheduling module are deployed on the management node, which is prone to single point of failure

That is, when the management node fails, it will lead to an error in the task assignment of the cluster system, and further, it will cause the cluster system to fail to successfully process the tasks it receives.
