Managing and Monitoring Jobs

Overview

Managing and monitoring your jobs effectively helps ensure efficient use of resources and enables quicker debugging when things go wrong. Slurm provides several built-in commands to track job status, usage, and troubleshoot issues.

SLURM has numerous tools for monitoring jobs. Below are a few to get started. More documentation is available on the SLURM website.

The most common commands are:

  • List all current jobs: squeue
  • Job deletion: scancel [job_id]
  • Run a job: sbatch [submit script]
  • Run a command: srun <slurm options> <command name>

SLURM User Commands

Task Command
Job submission: sbatch [script_file]
Job deletion: scancel [job_id]
Job status by job: squeue [job_id]
Job status by user: squeue -u [user_name]
Job hold: scontrol hold [job_id]
Job release: scontrol release [job_id]
List enqueued jobs: squeue
List nodes: sinfo -N OR scontrol show nodes
Cluster status: sinfo

Use these commands to manage and monitor your jobs

  • The seff command is a handy tool to assess how efficiently your job used the requested resources after it has completed.
  • Using seff can help you adjust your future job scripts to request only as much memory/time as truly needed, improving scheduler fairness and reducing wasted resources.

$ seff
Usage: seff [Options] <Jobid>
       Options:
       -h    Help menu
       -v    Version
       -d    Debug mode: display raw Slurm data
Example output

$ seff 575079

Job ID: 575079
Cluster: wulver
User/Group: ls565/ls565
State: COMPLETED (exit code 0)
Cores: 1
CPU Utilized: 00:00:19
CPU Efficiency: 67.86% of 00:00:28 core-walltime
Job Wall-clock time: 00:00:28
Memory Utilized: 4.21 MB
Memory Efficiency: 0.11% of 3.91 GB
  • The squeue command lets you check all the jobs currently running/pending/queued in the Wulver.
  • You can use squeue -u $LOGNAME to check your your jobs in the queue.

Example Output 

$ squeue
