User = a user who has been created in Unix and then added to slurmdbd (the 
second part is essential)
Account = A Slurm entity that can be thought of as a project or bank account 
(the term used in the documentation).

You also need to add the user to slurmdbd too!

That is my understanding.  I've never used GrpTRES for a user, only on 
accounts.

Yes, that's - they can use no more than 1,500 CPU cores across the whole 
cluster.

All the best,
