Partitions / Queues
The SLURM scheduler on Anunna divides compute nodes into separate partitions (sometimes called queues). When you submit a job, you choose which partition it runs in by setting --partition on your sbatch script.
Available partitions
- main — the default partition for CPU jobs. Use this unless you have a specific reason to pick another.
- gpu — for jobs that need NVIDIA GPUs.
- gpu_amd — for jobs that need AMD GPUs.
To see the partitions currently available on the cluster, run:
sinfo
This lists every partition together with its state and the nodes that belong to it.
Selecting a partition
The default partition is main. If you don't specify --partition, your job runs there. To select a different one, add a directive to your sbatch script:
#SBATCH --partition=gpu
For GPU partitions you also need to request the GPU itself as a generic resource — see Choosing a node (constraints) for the details.
