Task scheduling method and system and electronic equipment

Abstract

The embodiment of the invention discloses a task scheduling method and system and electronic equipment. A waiting task sequence and an unconnected task sequence are sent to a connecting thread through a logic thread; the tasks in the unconnected task sequence are tasks which are established by the logic thread and do not have dependent tasks; a target task is inquired in the unconnected task sequence through the connecting thread, the target task is a task in the unconnected task sequence, and the post-task comprises at least one uncompleted task in the waiting task sequence; if the target task is queried, the target task is sent to the logic thread through a connecting thread; and the target task is inserted into a logic thread task lockless queue through the logic thread, so that the connecting thread and the working thread steal and execute the target task. Through interaction of the logic thread and the connecting thread, the purpose of preferentially processing the waiting task sequence is achieved, so that the execution waiting time of the waiting task sequence is shortened, and the execution efficiency of the waiting task sequence is improved.

Description

technical field [0001] The present application relates to the technical field of computer applications, and more specifically, to a task scheduling method, system and electronic equipment. Background technique [0002] In a multi-threaded concurrent task scheduling system that supports task dependencies, if the execution of one task A depends on the execution of another task B, then task A cannot be executed until task B is completed. In some scenarios, there is a need to execute a specific task sequence. Based on this, if the execution of a task in a specific task sequence depends on the execution of at least one other task (the other task does not belong to the specific task sequence), then the specific task sequence The task needs to wait for at least one of the above-mentioned other tasks to be executed before it can be executed, and when other tasks are executed is uncertain, resulting in low execution efficiency of a specific task sequence.

Based on this, if the execution of a task in a specific task sequence depends on the execution of at least one other task (the other task does not belong to the specific task sequence), then in the specific task sequence The task needs to wait for at least one of the above-mentioned other tasks to be executed before it can be executed, and when other tasks are executed is uncertain, resulting in low execution efficiency of a specific task sequence
