If you want to use a GPU for your computations:
- Use one of the gpu... partitions (see table above)
- Choose a GPU according to your needs: single- or double-precision, VRAM etc.
- You can use the batch system to reserve only some of the GPUs. Use Slurm's generic resources for this.
You can for example write #SBATCH --gres=gpu:1 to get only one GPU. Reserve CPUs accordingly.
Below you will find an example job script which reserves 6 CPUs and 1 GPU on the gpuv100 partition.
Please do not reserve a whole GPU node if you are not using all available GPUs and do not need all available CPU cores! This allows more users to use the available GPUs at the same time!
