The following GPU partitions are available on the GPU partition of system Lise.
| Partition name | Node number | GPU hardware | Description |
|---|---|---|---|
| gpu-a100 | 42 | 4x A100 per Node | full node exclusive |
| gpu-a100:shared | FIXME | 1 to 4 A100 | shared node access, exclusive use of the requested GPUs |
| gpu-a100:shared:mig | 1 | 1 to 28 1g.10gb A100 MIG slices | shared node access, shared GPU devices via Multi Instance GPU. Each of the four GPUs is logically split into usable seven slices with 10 GB of GPU memory associated to each slice |
Example: exclusive usage of nodes
> srun --nodes=2 --partition=gpu-a100 example_cmd
shared usage of a node
> srun --gpus=2 --partition=gpu-a100:shared example_cmd
Multi Instance GPU slice on the according partition
> srun --gpus=1 --partition=gpu-a100:shared:mig example_cmd
