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:
