Overview

Slurm is an open source, fault-tolerant, and highly scalable cluster management and job scheduling system for large and small Linux clusters. Slurm requires no kernel modifications for its operation and is relatively self-contained. As a cluster workload manager, Slurm has three key functions. First, it allocates exclusive and/or non-exclusive access to resources (compute nodes) to users for some duration of time so they can perform work. Second, it provides a framework for starting, executing, and monitoring work (normally a parallel job) on the set of allocated nodes. Finally, it arbitrates contention for resources by managing a queue of pending work.

We provide a set of 2 appliances to easily deploy a Slurm cluster: Slurm Controller and Slurm Worker.

Requirements

Since the Slurm daemons (slurmctld and slurmd) are very lightweight, the minimum hardware requirements are low.

• OpenNebula version: >= 6.4
• Slurm Controller
  • Minimum CPU: 2CPUs
  • Minimum Memory: 2GB
  • Minimum Disk: 10GB
• Slurm Worker
  • Minimum CPU: 1CPU
  • Minimum Memory: 1GB
  • Minimum Disk: 7GB

Release Notes

Details for each release are available on the release page, providing comprehensive information about every version. The Slurm appliances are based on Ubuntu 24.04 LTS (for x86-64).
