suite u-be699 - coupled task fails

Reported by: xd904476 Owned by: ros
Component: UM Model Keywords:
Cc: Platform: ARCHER
UM Version:


I am having issues with my suite run again: ever since yesterday the coupled task of 2090 gets submitted and it fails after a short amount of run time. I am not sure about why.
Any suggestions?

Hi, What computer are you running the suite on? What error messages are you seeing?

Hi Dani,

You have somehow managed to get multiple occurances of the coupled task running for the current cycle and they are unsurprisingly interferring with each other. Can you please kill the currently running coupled task in the cylc GUI and then on ARCHER do:

qstat -u dflocco

and then kill the listed jobs with qdel <job id>.

Then retrigger the coupled task.

Hi Willie and Ros,
yesterday a couple task was showing a failure and was retrying very often. Not sure about why it would be running moltiple times. I think at some point I did set it to "ready" after a failure.

I've set it to run again now. Thanks

Hi Dani,

I took a look at your logs and it looks like there was an issue with qsub on ARCHER which meant the cylc couldn't check on the status of the job and thus deemed it had failed. It then tried 5 or so times to resubmit it until it succeeded and thus you ended up with 2 jobs running.

I've sent the details to ARCHER.

CMS note for completeness: Cray identified that this problem was due to a faulty blade which now been resolved.
