Node capacity expansion method, device and equipment of slurm scheduling system and medium

Abstract

The invention relates to a node capacity expansion method and device of a slm scheduling system, equipment and a medium. The method comprises the following steps: receiving a node capacity expansion request sent by a terminal; when a newly added node in the node capacity expansion request exists in a target cluster deployed by the slm scheduling system, acquiring a slm scheduling configuration file; when the slm scheduling configuration data of the newly added node does not exist in the slm scheduling configuration file, sending an installation request of a slm client to the newly added node; and when notification information of installation completion is received, acquiring slm scheduling configuration data of the newly added node, updating the slm scheduling configuration data to the slm scheduling configuration file, and performing node expansion by the slm scheduling system. According to the method and the device, automatic capacity expansion is realized, the tedious steps of manually inputting a command and realizing capacity expansion in the prior art are solved, and the node capacity expansion efficiency of the slm scheduling system is improved.

Description

technical field [0001] The present application relates to the technical field of data processing, in particular to a node expansion method, device, equipment and medium of a slurm scheduling system. Background technique [0002] Slurm is an open source, fault-tolerant, highly scalable cluster management and job scheduling system for large and small Linux clusters. It provides three key functions. First, it assigns users exclusive and / or non-exclusive access to resources (computer nodes) for a period of time so they can perform work. Second, it provides a framework for launching, executing, and monitoring jobs (typically parallel jobs, such as MPI) on an assigned set of nodes. Finally, it arbitrates resource contention by managing a queue of pending jobs. In practical applications, the computing power of the slurm scheduling system is often insufficient. In this case, it is necessary to expand the capacity of the slurm scheduling system. [0003] At present, when the slur...

Problems solved by technology

[0003] At present, when the slurm scheduling system needs to be expanded, the expansion of nodes is generally achieved through various command operations. This solution requires manual intervention, and the steps are cumbersome and inefficient.
