Slurm clusters

  • The new Slurm CPU cluster is called merlin6.
  • The new Slurm GPU cluster is called gmerlin6
  • The old Slurm merlin cluster is still active and best effort support is provided. The cluster, was renamed as merlin5.

From July 2019, merlin6 becomes the default Slurm cluster and any job submitted from the login node will be submitted to that cluster if not .

  • Users can keep submitting to the old merlin5 computing nodes by using the option --cluster=merlin5.
  • Users submitting to the gmerlin6 GPU cluster need to specify the option --cluster=gmerlin6.

Slurm 'merlin6'

CPU nodes are configured in a Slurm cluster, called merlin6, and this is the default Slurm cluster. Hence, by default, if no Slurm cluster is specified (with the --cluster option), this will be the cluster to which the jobs will be sent.
