All,

Don’t quite get this:

# squeue|head

JOBID PARTITION NAME USER ST TIME NODES NODELIST(REASON)

751071_17703 primary PARAMEIG clwalton CG 3-00:00:19 1 compute-3-87

787294 primary wrfrunmp hale R 3:34:03 1 compute-7-1

# squeue -u clwalton

squeue: error: Invalid user: clwalton

JOBID PARTITION NAME USER ST TIME NODES NODELIST(REASON)

# squeue -u hale

JOBID PARTITION NAME USER ST TIME NODES NODELIST(REASON)

787831 primary runwrfam hale PD 0:00 1 (Reservation)

787294 primary wrfrunmp hale R 3:34:03 1 compute-7-1

Clearly user clwalton is a valid user and has jobs running, but if I try to specify him, squeue isn’t happy. It is fine with other users…

What would cause this?

Hi Brian,

Is there actual username longer than 8 characters? The default squeue format
includes "%.8u" for the username.

Paddy,
Nope, it is exactly 8 characters: clwalton

Hi,

Is the user defined in all the compute nodes? Does it has the same UID in all the hosts?

Regards,

Carlos

Carlos,

Yes. The cluster uses LDAP for users.

I take that back. It was indeed the issue. User name is clwalton1...
Doh!

Thanks for pointing me in the right direction.
