Abstract

The embodiment of the invention discloses a distributed task processing method and device. The distributed task processing method comprises the steps that calculating nodes monitor at least one health index value of the calculating node through a daemon process; the calculating nodes judge whether the calculating node has the permission of taking subtasks from a task pool prestored with a plurality of subtasks or not according to the health index values and preset threshold values corresponding to the health index values; if yes, the calculating nodes take at least one subtasks from the task pool prestored with a plurality of subtasks; the calculating nodes generate task threads corresponding to the taken subtasks and utilize the task threads to execute the subtasks. By utilizing the embodiment, the problem that in an existing distributed task processing technology, the scale of calculating node groups is limited due to the fact that the subtasks are dispatched to a plurality of calculating nodes through connection between control nodes and a plurality of calculating nodes and through the control nodes can be solved.

Description

technical field [0001] The present application relates to the field of computer application technology, in particular to a method and device for distributed task processing. Background technique [0002] In a distributed environment, a distributed task to be processed is usually split into multiple subtasks, and each subtask obtained after splitting is distributed to several computing nodes for processing. [0003] In the prior art, the subtask processing method in a distributed environment is generally implemented by control nodes and computing nodes, which may specifically include the following process: the control node establishes a heartbeat connection with each computing node to obtain the health status of each computing node Status information (for example: number of database connections, CPU usage and memory usage, etc.). The control node distributes the pre-stored subtasks in the task pool to corresponding computing nodes for processing according to the acquired hea...
