How do I submit a job to a GPU node via Slurm?

If your default Slurm association/account does not have GPU partition access. And if you want to request GPU from another account, you can request it using the flags:

#SBATCH --account=Alternate_Account_Name
#SBATCH --nodes=1
#SBATCH --gres=gpu:1

Or when you submit your job using srun, add these flags:

srun -A Alternate_Account_Name --gres=gpu:1 -t 01:00:00 --mem=20GB
