Task scheduling methods, resource sharing usage based on preemptive scheduling and systems, schedulers, devices, and computer-readable storage media

摘要

The embodiments of the present invention disclose resource sharing usage methods, systems and devices based on preemptive scheduling, which are prioritized when the API server creates a task and when the scheduler processes the current task. Based on this, the target physical node that best matches the predetermined screening conditions is screened, the current task and the target physical node banding information are sent to the API server, and the physical node is waiting to be executed in the task queue. When processing a target task, get a list of tasks running on the physical node, and if the physical node detects that the remaining resources do not meet the resources required to run the target task. Prioritize tasks that have a lower priority in the task list than the target task, until the remaining resources obtained by the physical node executing the task in the task list meet the resources required to execute the target task. Includes moving to the queue waiting to be deleted in ascending order of, and preempting tasks in the queue waiting to be deleted. [Selection diagram] Fig. 6
