Queue instance in au state

When qstat show the queue in au state that simply means that Grid Engine is likely not running on the node. The "a" means 'alarm' and the "u" means unheard/unreachable. The combination of the two more often than not means that SGE is not running on the compute node.

The "E" state is more of a concern than the 'au' state.

'au' simply means that Grid Engine is likely not running on the node. The "a" means 'alarm' and the "u" means unheard/unreachable. The combination of the two more often than not means that SGE is not running on the compute node.

E is a worse state to see. It means that there was a major problem on the compute node (with the system or the job itself). SGE intentionally marked the queue as state "E" so that other jobs would not run into the same bad problem.

E states do not go away automatically, even if you reboot the cluster. Once you think the cluster is fine you can use the "qmod" command to clear the E state.

Hi, I don't know anything about apple systems, but the E state for the q's is error, look in the messages file under the $sge_root/$cell/ qmaster directory for messages indicating the job causing the problem. The au state normally indicates the sge exec daemon which should be running on the execution host is not and needs to be restarted.

Hi All,

Our Apple cluster running Grid Engine 6 is sick, the "qstat -f" output is like:

queuename qtype used/tot. load_avg arch states BIP 0/2 0.03 darwin E


all.q@node001.cluster.private BIP 0/2 0.09 darwin E

all.q@node004.cluster.private BIP 0/2 0.00 darwin E


all.q@node005.cluster.private BIP 0/2 0.00 darwin E

... Followed by a long and growing pending list.

What is the way to tackle "au" states?  Any input would be appreciated!
