Abstract

The embodiment of the invention discloses a task scheduling method, a device, an electronic device and a storage medium. The method comprises the following steps: traversing the tasks in the current queue to obtain the current state information of the traversed tasks and the current values of frequency parameters; according to the current state information of each task and the current value of thefrequency parameter, selecting the task whose current state information is the least scheduled frequency among the tasks that can be executed as the target task; the selected target task being executed and the current value of the frequency parameter corresponding to the target task being updated after the target task is executed. By introducing frequency parameters to determine target tasks, theproblem of unbalanced task scheduling in the prior art is solved, and the stability of the task scheduling process is improved.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of computers, and in particular, to a task scheduling method, device, electronic equipment, and storage medium. Background technique [0002] At present, the algorithm modules operated by the unmanned vehicle system include perception, planning, control, vehicle status detection, positioning, etc. These algorithm modules are connected through information channels to form a complex directed acyclic graph (DAG) topology. A typical feature of the topological structure of the unmanned vehicle is that different nodes send and receive data at different frequencies, and because of the correlation of different nodes in the DAG, the unmanned vehicle scheduling system is more complicated than the traditional server-side scheduling algorithm. [0003] Specifically, each node in the DAG topology corresponds to a task. When the data required to execute a certain task is generated, the state of t...
