Using the slurm batch system

The GPU nodes are available via Slurm partitions GPU A100.Lise's CPU-only partition and the A100 GPU partition share the same SLURM batch system. The main SLURM A100 shares the same slurm batch system with all partitions of System Lise.

• A general introduction to the batch system you find Slurm usage.
• Slurm partitions GPU A100 describes the specific properties of slurm for the GPU A100 partition. The main slurm partition for the A100 GPU partition has the name "gpu-a100". An example job script is shown below.
