[slurm-users] Regarding Multi-Cluster Accounting Information

[Yair Yarom]

Hi,

We have several clusters on the same database. There are some entities
which are per cluster and some which are per database.
accounts - per cluster (you can have same account name with a different
account hierarchy, and different limits per cluster)
association - per cluster
qos - per database (we prefix our qos name with the cluster name to
distinguish).
partitions/nodes - per cluster (not really in the database though)
users - I'm not sure. On one hand an admin user is an admin for all
clusters. On the other hand, a user can have a different default account
per cluster.

HTH,
