Simple Sequential Slurm Job

This is the basis of most common, sequential Slurm jobs and can be extended easily by adjusting the CPU, RAM and runtime resources. Items to note are:

  • Uses the HPC Project group myhpcproject; change to use your real HPC Project name
  • Submitted to the free default_free partition (–partition=default_free)
  • Requests 1 CPU (–cpus-per-task=1)
  • Requests 1GB of RAM (–mem=1G)
  • Requests up to 10 hours of runtime (–time=10:00:00), for a maximum possible total of 10 Compute Hours (cpus_per_task * time_in_hours)
  • Prints the time the job started to the log file
  • Prints the name of the compute node(s) it will run on
  • Prints the time the job finished to the log file

#!/bin/bash

#SBATCH --account=myhpcproject
#SBATCH --partition=default_free
#SBATCH --cpus-per-task=1
#SBATCH --mem=1G
#SBATCH --time=10:00:00

# Log when we started
echo "Job started at: `date`"

# Show which node(s) we are running on
HOSTNAMES=`scontrol show hostnames $SLURM_JOB_NODELIST`
echo "Job is running on: $HOSTNAMES"

# Add any 'module load' commands here

# Add your custom commands you want to run here

# Log when we finished
echo "Job finished at: `date`"
