• sinfo shows existing queues
• scontrol show job <JobID> shows information about specific job
• sstat <JobID> shows resources used by a specific job
• squeue shows information about queues and used nodes
• smap curses-graphic of queues and nodes
• sbatch <script> submits a batch job
• salloc <resources> requests access to compute nodes for interactive use
• scancel <JobID> cancels a batch job
• srun <ressources> <executable> starts a (parallel) code
• sshare and sprio give information on fair share value and job priority

Do's & Don'ts

• Do not use srun for simple non-parallel jobs like cp, ln, rm, g[un]zip
• Make use of parallel srun p[gu]igz instead of g[un]zip if you have allocated more than one CPU already
• Do not allocate costly resources (like fat/gpu nodes) if you not need them. Check the CPU/Memory-Efficiency of your jobs with info.sh -S
