Dear CMS team, I am currently working on the self-study practice by following the UM introduction file I received during the training course in Leeds. I am currently on 6.4.1. Check out and run the suite. Since I followed the instructions to run the suite u-dw272, the TUI for this suite looks like this: ![image](https://europe1.discourse-cdn.com/flex013/uploads/cms_support/original/1X/fd791ef397e990c77a2a5940314ab11254ca4e5b.png) No matter how long I have been waiting for, the cycle seems stuck, as it shows pink squares on it. Thus, I wondered if you could help me with this issue? I have checked my storage space, and I think I have not run out of it. Is it probably the difference between the onsite training and self-study (I noticed a comment on the front page of the introduction file, that says I need to contact you for instruction while self-studying)? Kind regards, Lucky ---

Hi Lucky, The pink squares indicate submission failure and if you navigate to one of them and hit return you should see a menu pop up giving you the option to view the log files. Alternatively you can view the log files on PUMA2 under `/home/n02/n02/gxz376/cylc-run/u-dw272/run2/log/job` In e.g. `/home/n02/n02/gxz376/cylc-run/u-dw272/run2/log/job/19780901T0000Z/fcm_make2_ocean/10/job-activity.log` the error message is: ```auto 2026-05-28T02:48:28Z [STDERR] sbatch: error: AssocMaxCpuMinutesPerJobLimit 2026-05-28T02:48:28Z [STDERR] sbatch: error: Batch job submission failed: Job violates accounting/QOS policy (job submit limit, user's size and/or time limits) ``` This indicates either you are using an invalid account code, the timelimit requested is too much or you have too many jobs already in the queue. Looking at the job setup you are trying to run under account code `n02` which is invalid. I have put a small number of CUs into the `n02-training` budget so you can use that whilst you are working through the training material. Once you start running your own jobs you will need to be added to the budget code for your project. Cheers, Ros ---

Hi Ros, Thank you very much for your help, and it is now back to work. I think the submission failure arose because I previously ran out of the CU for practice. Best, Lucky ---
