Running jobs on proprietary nodes

Research groups who have made use of the buy-in option (bought own hardware to be hosted in AI Cloud) will have privileged access to their nodes.

Other users can also make use of the resources with unprivileged access.

Privileged access

AI Centre

Researchers with affiliation to the Pioneer Centre for AI can be added to the following privileged accounts:

• aicentre

  This account gives access to the partition of the same name aicentre containing the nodes i256-a40-01 and i256-a40-02.

  To launch a privileged job on this node, the --account= and --partition= arguments must be added to your launch command:

  ❯ srun --partition=aicentre --account=aicentre hostname
  srun: job 793360 queued and waiting for resources
  srun: job 793360 has been allocated resources
  i256-a40-01.srv.aau.dk
  

• aicentre-a100

  This account gives access to the partition of the same name aicentre-a100 containing the node nv-ai-04.

  To launch a privileged job on this node, the --account= and --partition= arguments must be added to your launch command:

  ❯ srun --partition=aicentre-a100 --account=aicentre-a100 hostname
  srun: job 793361 queued and waiting for resources
  srun: job 793361 has been allocated resources
  nv-ai-04.srv.aau.dk
  

Unprivileged access

If you want wish to launch an unprivileged job on a proprietary node, you must specify the arguments; --partition=, --qos= and --time arguments:

❯ srun --qos=unprivileged --partition=aicentre --time=0-00:01:00 hostname
srun: job 793362 queued and waiting for resources
srun: job 793362 has been allocated resources
i256-a40-01.srv.aau.dk

Please note:

• The --time= parameter can be set to a maximum of 6-00:00:00 (6 days).

• Unprivileged jobs are preemtable. If a request is made for the same resources, the job will be interrupted until the resources free up again.
