Slurm is an open-source job scheduler for Linux and Unix-like kernels.

SRUN

srun is used to submit jobs for execution in real time. Also used to create job steps.

srun example

srun --pty /bin/bash                                                   # shell on compute job / default account is used when not specified 

srun -p slurm-general-01 --account=slurmgeneral --pty /bin/bash        # shell on compute job / specifying which partition and account (applicable if user is assigned multiple accounts)

SBATCH

Sbatch is a command used to submit batch scripts to Slurm.

batch script example

#!/bin/bash -l                             # login shell (required for lmod)                             
#SBATCH --job-name=testprogram             # job name
#SBATCH --partition=slurm-general-01       # specifying which partition to run job on
#SBATCH --account=slurmgeneral             # only applicable if user is assigned multiple accounts
#SBATCH --ntasks=1                         # request 1 CPU
#SBATCH --mem=1gb                          # request 1gb of memory
#SBATCH --output=testprogram.lob           # output and error log

submitting a job using sbatch

sbatch myprogram.sh                                                  # queue job using a batch script 

sbatch -p slurm-general-01 --account=slurmgeneral myprogram.sh       # batch script specifying which partition and account when not specified using a slurm directive within the script
