Submitting Course Jobs

Submit scripts on Wulver must include specification of partition, account, qos, and time limit. Also the first line in the batch file must be #!/bin/bash -l.

Below is the minimal example for a 10-minute test job:

1

#!/bin/bash -l
#SBATCH --partition=course
#SBATCH --account=2025-fall-ds-492-kjc59-ls565
#SBATCH --qos=course
#SBATCH --time=00:10:00

Sample Job scripts

Make sure to replace --account with your assigned course account.

#!/bin/bash
#SBATCH --job-name=test_gpu_job
#SBATCH --output=%x.%j.out
#SBATCH --error=%x.%j.err
#SBATCH --partition=course_gpu
#SBATCH --account=2025-fall-ds-492-kjc59-ls565
#SBATCH --qos=course
#SBATCH --time=00:20:00
#SBATCH --ntasks=2
#SBATCH --gres=gpu:a100_10g:1

# Load application environment
module load CUDA

# Run application commands
nvidia-smi
  • Runs a GPU job named test_gpu_job.
  • Allocates 2 CPUs and single A100 10G MIG GPU.
  • Wall time: 20 minutes.

Limitation of GPU Jobs

  • You cannot request multiple MIG instances in one job.
    For example: --gres=gpu:a100_10g:2
    This will either cause an error or misinterpretation as a single GPU.

  • Each job should request one GPU per job.
    For multiple tasks, use job arrays instead of multiple MIGs.

Interactive jobs

You can also start an interactive session instead of a batch job.

1
interactive -a ACCOUNT -q QOS -p PARTITION -j JOB_TYPE

Parameters:

  • -a ACCOUNT → Your assigned course account
  • -q course → QoS for course jobs
  • -p course → Partition (use course or course_gpu)
  • -j JOB_TYPE → Type of job (e.g., cpu or gpu)

Example

1
interactive -a 2025-fall-ds-492-kjc59-ls565 -q course -p course

This command launches a temporary compute session for hands-on work or testing.
