The following GPU partitions are available on the GPU partition of system Lise.
...
GPU A100 shares the same slurm batch system with all partitions of System Lise. The following slurm partitions are specific for the GPU A100 partition.
...
| Slurm partition | Node number | CPU | Main memory (GB) | GPUs per node | GPU hardware | Walltime (hh:mm:ss) | Description |
|---|---|---|---|---|---|---|---|
| gpu-a10036 | 34 | Ice Lake 8360Y | 1000 | 4 | NVIDIA Tesla A100 80GB | 24:00:00 | full node exclusive |
| gpu-a100:shared | 5 | 4 | NVIDIA Tesla A100 80GB | shared node access, exclusive use of the requested GPUs | |||
| gpu-a100:shared:mig | 1 | 28 (4 x 7) | 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 |
Cost: 150 core hours per GPU or 21.43 per MIG slice
