Hi Sergio:
Those jobs aren't queued, they're running.
Don't know why nodes aren't being removed though .... has it been 55 minutes (I think that's the default)?
Cheers, Hugh

Hi all,
Just followed the tip from Hugh MacMullan (submit a ghost job to restart the stats to begin loadbalancing starcluster but still got some strange info.
At this present time, the queue has 3 jobs:
sgeadmin at master:~/gpo2/PEN_2013/GTBase/caso4$ qstat
job-ID prior name user state submit/start at queue slots ja-task-ID
-----------------------------------------------------------------------------------------------------------------

3 0.50500 c5 sgeadmin r 05/22/2013 14:30:23 all.q at node001<mailto:all.q at node001> 53
4 0.60500 c6 sgeadmin r 05/22/2013 14:30:38 all.q at node001<mailto:all.q at node001> 54
But StarCluster LoadBalancer doesn´t understant that... It says Queued Jobs: 0
>>> Loading full job history

Sergio:
One job needs to run to completion before the stats are available to begin loadbalancing in StarCluster. Like:
echo hostname | qsub -o /dev/null -j y
It's funny, I just ran into those same two issues (timezone and no completed job) recently while fiddling with my own AMIs and loadbalancing.

Hi Sergio,
Sorry for the delayed response. Busy week at work. Adding starcluster alias back, in case this helps other people in the future.
Like I said, I'm not sure why your instance is coming up with PDT in the EC2 instance, since from what I remember it would always return UTC.
Is it possible for you to download the latest dev version if you haven't tried that already?
http://star.mit.edu/cluster/docs/latest/contribute.html
Slightly different directions than the one you specified. Then, you can modify this file:
starcluster/balancers/sge/__init__.py line 466
To replace UTC with PDT. Then run the ELB, and it'll run the latest code. Let me know if that works, and we can file a bug and go through the formal process of letting you switch the timezone. I'm guessing that you're pretty familiar with python programming, but if you have more problems then feel free to ask more questions.
Best,
Rajat

Hi Rajat,
Thanks so much for your kindness in order to find out where this error was. Nice!
It´s a little bit odd to understand what is causing that since I´m using the SC Controller as an instance in the same zone (us-east-1d) as the cluster launched by it. So this should be in the same time format...???
What I did was donwload the code directly from the GIT´s site and compile it as described in http://star.mit.edu/cluster/docs/latest/installation.html
???
All the best,
Sergio

Sergio,
I looked at the code that is causing your problems. It's this line:
return datetime.datetime.strptime(str, "%a %b %d %H:%M:%S UTC %Y")
where 'str' is the output of the *remote* call to date. My mac returns this:
rbanerjee:~/starcluster/StarCluster/starcluster/balancers/sge $ date
Tue Apr 30 13:12:44 EDT 2013
Which looks like it would time format OK. One oddity is that your time format is returning PDT when UTC is expected:
ValueError: time data 'Tue Apr 30 07:01:35 PDT 2013' does not match format '%a %b %d %H:%M:%S UTC %Y'
Not sure what's causing the problems since it looks mostly right, but feel free to tweak the time setting in the code in starcluster/balancers/sge/__init__.py line 466 to make the pattern match yours. Do you know why your time zone may be set differently than other AWS instances we've used? Custom images?
Best,
Rajat

Hi,
I am a beginner of using the StarCluster. I created a ebs volme via Amazon AWS and configure it on the config file to use it for my cluster, but no matter what I do, it doesn't automatically mount the ebs volume onto the cluster. Please help.
