 ??? I'm using Open XDMoD to check how many hours my group used this year, but the amount is quite different from what appears on the invoice or in ''ug_slurm_usage_per_user.py''.
-!!! For invoicing, we use a Slurm metric called billing. This metric aggregates CPU hours, memory usage, and GPU usage. Unfortunately, Open XDMoD does not currently support this metric. We have added a warning about this in our documentation.

 ??? I'm a user and I've noticed that I'm connected to two PIs, how is this possible?
 !!! The PI must be seen as a project. You can be part of two projects, and when you submit a job to the cluster, you can specify which project to charge to using the ''<nowiki>--account</nowiki>'' flag.
+You can check who is your PI and which is your default account with the following command:
+<code>
+sacctmgr show user <your_username> -s format=user,account,defaultaccount cluster=baobab
+      User    Account   Def Acct
+---------- ---------- ----------
+  username acct1       xxx
+  username acct2       xxx
