Node states
To see the current states of the nodes in ARC's partition you can use the arc.nodes command:
$ arc.nodes
Partitions: 16 (bigmem, cpu2017-bf05, cpu2019, cpu2019-bf05, cpu2021, cpu2021-bf24, cpu2022,
cpu2022-bf24, cpu2023, disa, gpu-a100, gpu-v100, ood-vis, parallel, single, wdf-altis)

- The first column on the left shows the partition names. Each line presents information about this specific partition.
- The second column, Total, indicates the total number of nodes in this partition.
- The following columns show node states. The table is built dynamically, so it only shows the states which currently present in ARC.
- These are standard SLURM states and their description can be found in SLURM documentation:
