Abstract

The invention provides a task resource reservation method and device, and the method comprises the steps: selecting a second node set from a first node set, wherein the first node set comprises one ormore first nodes, and the second node set comprises one or more second nodes which can be used for resource reservation; selecting a target node from the one or more second nodes according to the first running moment information of the second nodes so as to perform resource reservation processing on a to-be-scheduled task, wherein the first running time information is used for indicating the completion time of the current running task of the second node. Through the resource reservation method and device, the problem that the system resource utilization rate is reduced due to idle node resources in the resource reservation process in the prior art can be solved, so that the effect of improving the system resource utilization rate in the resource reservation process is achieved.

Description

technical field [0001] The present invention relates to the field of computer software, in particular to a task resource reservation method and device. Background technique [0002] Cluster management systems, such as OpenPBS, need to reserve resource nodes in the system during task scheduling. At present, the reservation strategy in related technologies is usually that when a task waits in the queue for more than a certain length, it can reserve the node resources it needs, that is, when some of these node resources become available, no It is then assigned to other tasks, and the task is put into operation until all reserved resources are satisfied. [0003] Although the above reservation strategy can alleviate the phenomenon that tasks with large resource requirements cannot be run for a long time to a certain extent, resource fragments will be generated during the above resource reservation process; figure 1 It is a schematic diagram of resource and time distribution du...
