SGE queue states and state codes

Queue states or combinations of states can be

• a(larm) alarm by reaching the limit of load. See Queue instance in AU state
  
• A(larm) by reaching the limit of suspension.
  
• s(uspended)
• S suspended by subordination.
   
• C suspended by a timetable.
   
• d(isable) See Excluding SGE execution host from scheduling
  
• D(isable) See Excluding SGE queue from scheduling
  
• E(rror)  See Job or Queue Reported in Error State E. If the "state" column in qstat -f  has a big E, that host or queue is in an error state due to... well, something. Sometimes an error just occurs and marks the whole queue as "bad", which blocks all jobs from running in that queue, even though there is nothing otherwise wrong with it.

  Use qmod -c <queue list>  to clear the error state for a queue.

   

• U  -- unheard/unreachable. see 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.

Combinations

• au - means that communication with node is broken. Possibly the execd daemon is not running.  In this case you have -NA- in load average for the node: 

  all.q@wx3481              BIP   0/0/8          -NA-     lx24-amd64    au

  Maybe there is some network problem preventing the SGE master from communicating with the exec host, such as routing problems or a firewall misconfiguration.  Once I have the case when there was a mismatch of hostnames

• Eqw -- typically means that execution agent is not running or NFS is available or both

SGE quick and dirty how to find jobs on 'bad' slots () By yakshaving

Nov 26, 2007 YakShaving Shawn Ferry's Weblog

I occasionally have a need to find queues in Sun Grid Engine that are in one of the possibly problematic states which have an occupied slot. It is just infrequent enough that I don't remember exactly how I did it the last time.

qstat -f | awk '$6~/[cdsuE]/ && $3!~/\^[0]/'
queuename                      qtype used/tot. load_avg arch          states
[email protected]   BIP   1/1       -NA-     sol-amd64     adu
[email protected]   BIP   1/1       -NA-     sol-amd64     adu

An alternate is "qstat -f | awk '$6~/[cdsuE]/ && $3~/\^[1-9]/'" which also avoids printing the header line. In the example above 'state' in $6 matches 's' and 'used' does not begin with '0'.

The possibly more elegant 'qstat -f -qs cdsuE' still requires a second comparison in awk of '$0!~/--/' to filter out the queue separator lines. (qstat -f -qs acduE | awk '$0!~/--/ && $3!~/\^[0]/')

Finally because I can never remember what exactly all the queue states are and the qstat man page doesn't have the nice table:

aoACD – Number of queue instances that are in at least one of the following states:
a – Load threshold alarm
o – Orphaned
A – Suspend threshold alarm
C – Suspended by calendar
D – Disabled by calendar

cdsuE – Number of queue instances that are in at least one of the following states:
c – Configuration ambiguous
d – Disabled
s – Suspended
u – Unknown
E – Error

Job State/Status:

d(eletion), E(rror), h(old), r(unning), R(estarted), s(uspended), S(uspended), t(ransfering), T(hreshold) or w(aiting).

What it means is documented in the qstat man page, at least the one you
can get via the URL below.
