Simple Linux Utility for Resource Management – SLURM

SLURM (Simple Linux Utility for Resource Management) is an open-source workload manager and resource manager for clusters and supercomputers. It is used to manage and schedule jobs on large-scale computing systems, including tasks such as submitting jobs, allocating resources, and monitoring job progress.

SLURM is designed to be scalable, flexible, and easy to use. It is used by many high-performance computing (HPC) centers, research organizations, and government agencies around the world.

Here are some examples of how SLURM can be used:

  • Submitting a job: A user can submit a job to SLURM using the “sbatch” command. The user specifies the command to be run, the resources required (such as the number of CPUs and amount of memory), and any other job constraints (such as the time limit or dependencies on other jobs). SLURM will then allocate the necessary resources and schedule the job for execution.
  • Allocating resources: SLURM can be configured to allocate resources to jobs based on various criteria, such as the priority of the job, the availability of resources, and the policy specified by the administrator. For example, a user might submit a job that requires 8 CPUs and 32GB of memory. SLURM will then allocate those resources to the job and ensure that the job has exclusive access to them until it completes.
  • Monitoring job progress: SLURM provides tools for monitoring the progress of jobs, such as the “squeue” command, which shows the status of all jobs in the system. Users can use these tools to track the progress of their jobs and check for any issues or errors.

Overall, SLURM is a powerful and widely used tool for managing and scheduling jobs on large-scale computing systems. It is an essential tool for many HPC centers and other organizations that rely on large-scale computing resources.
