| | ====== Commands ====== |
| | |
| | \\ |
| | |
| | ===== Common Commands ===== |
| | |
| | - slurm (introduction) |
| | - launching jobs: **salloc** (resource reservation for jobs) && **srun** (jobs and job steps running tasks) |
| | - batch jobs: **sbatch** (batch jobs to queue) |
| | - **scancel** (signal/stop running jobs) |
| | - **sstat** (infos wrt. running jobs) |
| | - **squeue** (show queues) |
| | - sinfo (show node infos) |
| | |
| | ==== STUBL Tools ==== |
| | |
| | - snodes (list node features; wrapper for sinfo) |
| | - sqstat (list job queues and cluster status information) |
| | |
| | \\ |
| | |
| | ===== Manpages ===== |
| | |
| | * ''man 1 sbatch'' |
| | * ''man 1 srun'' |
| | * ''man 1 salloc'' |
| | * ''man 1 scancel'' |
