A job array is a specific type of Slurm job script that launches multiple of the same job to be executed at the same time (resources permitting). These kinds of jobs can be used for running the same script on multiple pieces of data or for doing something like a parameter sweep for running the same code with different values for inputs. The example Slurm job script below uses an array of 1-10 with commented out examples on how to do different types of arrays. The value of the array for each job can be accessed with $SLURM_ARRAY_TASK_ID

#!/bin/bash
  
## Specify the account to use; you must use your priority account.
#SBATCH --account=priority-<account-name-here>

## Use the priority partition.
#SBATCH --partition=priority

## Number of CPUs to allocate. Note that in the slurm, CPUs correspond to
## logical processors, not physical cores.
#SBATCH --cpus-per-task=16

## Amount of memory for the job.
#SBATCH --mem=32G

## Maximum job run time. Format is days-HH:MM:SS.
#SBATCH --time=0-01:00:00

## Set job name.
#SBATCH --job-name=jobArrayJob

## Set output log and error log filenames. 
## %j is the job number and %x is the job name set above 
#SBATCH --output=%x.out
#SBATCH --error=%x.err

## A job array with this argument launches multiple jobs that run the same code below with a unique identifier $SLURM_ARRAY_TASK_ID.
#SBATCH --array=1-10          # Launches three jobs with IDs 1, 2, and 3.
##SBATCH --array=1,3,5,7       # Launches four jobs with IDs 1, 3, 5, and 7.
##SBATCH --array=1-7:2         # Launches jobs with IDs counting from 1 to 7 in steps of 2 (1,3,5,7)
##SBATCH --array=1-10%5        # Launches jobs with IDs 1 to 10 with a limit of five at a time.

## Run 'man sbatch' for more information on the options above.
## Below, enter commands needed to execute your workload
