REPACSS Command Cheatsheet¶

Quick reference for commonly used commands and options on REPACSS.

Job Submission¶

sbatch job.sh                    # Submit a batch job
interactive -c 8 -p zen4         # Start an interactive session (recommended)
srun ./program                   # Run a job step

Tip

Always use the interactive command for starting real-time sessions. It properly configures the environment and avoids common issues that arise when using salloc directly.

Monitoring Jobs¶

squeue -u $USER                  # Show your jobs
sqs                              # Enhanced view of job queue
scontrol show job <jobid>       # Job details

Cancel Jobs¶

scancel <jobid>                  # Cancel specific job
scancel -u $USER                 # Cancel all your jobs
