PREEMPTIVE SCHEDULING BASED RESOURCE SHARING USE METHOD, SYSTEM AND

摘要

Disclosed are a resource sharing use method, system and device based on preemptive scheduling. The method includes: an API server creates a task; when a scheduler processes a current task, a target physical node best satisfying a preset screening condition is screened out based on the priority, and binding information between the current task and the target physical node is sent to the API server; when a physical node processes a target task to be run in a task queue, a task list of tasks running on the physical node is acquired; when the physical node detects that remaining resources of the physical node do not satisfy resources required for running the target task, at least one task, having a priority lower than a priority of the target task, in the task list is moved into a queue to be removed in a priority order from low to high until the remaining resources obtained after the physical node executes remaining tasks in the task list satisfy the resources required for running the target task, and at least one task in the queue to be removed is preempted.
