The BIH HPC uses the Slurm scheduling system.
This section of the manual attempts to give an overview of what scheduling is and how you can use the Slurm scheduler.
For more detailed information, you will have to refer to the Slurm website and the Slurm man pages (e.g., by entering
man sbatch or
man srun on the HPC terminal's command line).
For a quick introduction and hands-on examples, please see the manual sections
- Background on Scheduling -- some background on scheduling and the terminology used
- Quickstart -- explains the most important Slurm commands, with examples
- Cheat Sheet -- for quick reference
- Job Scripts -- how to setup job scripts with Slurm
- Memory Allocation -- memory allocation ( one of the most important concepts that is most often found confusing)
- Introduction to Slurm Commands
srun-- running parallel jobs now
sbatch-- submission of batch jobs
scancel-- stop/kill jobs
sinfo-- display information about the Slurm cluster
squeue-- information about pending and running jbos
scontrol-- detailed information (and control)
sacct-- access Slurm accounting information (pending, running, and past jobs)

A Word on "Elsewhere"¶
Many other facilities run Slurm clusters and make their documentation available on the internet. We list some that we found useful below. However, be aware that Slurm is a highly configurable and extensible system. Other sites may have different configurations and plugins enabled than we have (or might even have written custom plugins that are not available at BIH). In any case, it's always useful to look "über den Tellerrand".
