sbatch

Submit batch jobs to the Slurm scheduler

TLDR

Submit batch job

$ sbatch [job.sh]

Submit with custom name

$ sbatch --job-name=[myjob] [job.sh]

Set time limit

$ sbatch --time=[00:30:00] [job.sh]

Request multiple nodes

$ sbatch --nodes=[3] [job.sh]

SYNOPSIS

sbatch [--job-name name] [--time limit] [--nodes n] [--cpus-per-task n] [script]

sbatch submits batch job scripts to the SLURM workload manager. Jobs are queued and executed when requested resources become available on the cluster.Job scripts contain SLURM directives (lines starting with #SBATCH) specifying resource requirements, followed by commands to execute. SLURM handles job scheduling and resource allocation.

Resource requests affect queue wait time. Exceeding time limit kills job. Environment may differ from submission shell. Check partition limits with sinfo.

HISTORY

sbatch is part of SLURM (Simple Linux Utility for Resource Management), developed at Lawrence Livermore National Laboratory. SLURM is now the most widely used HPC job scheduler.
