Hi all, I’m running test-case simulations for the Lismore flood setup using ACCESS-rAM3, and I’m encountering an issue. The OAS and RAS suites appear to start normally, but the jobs seem to sit for an extended period (up to ~1 day) without progressing, and then eventually fail or get terminated. I…

Before closing I am just going to summarise at least the latest issue as that could be something other users encouter. When running a cylc suite, if you encounter failures of the type: Using the cylc session mlftcr.mm6452.if69.ps.gadi.nci.org.au Loading cylc7/24.03 Loading requirement: mosrs-setu…

It looks promising - Gadi session still hasn’t started so I can’t compare and I don’t usually look at the polling. If you go to the OSTIA_OUTPUT directory if it succeeded you will find the ancillary files there.

Hi @cbengel I did check the OSTIA_OUTPUT directory and I can see the ancillary files of 25th, 26th, and 27th. So I guess I ran the OAS successfully. When I started running the RAS suite this morning, I encountered this error on my ANCIL run: ERROR: file not found: /home/581/mm6452/cylc-run/u-bu503…

@Moulik For any job starting today my first suspicion would be problems due to Gadi going down. Please check that you have restarted your persistent session by running `persistent-sessions list`. If it isn’t there you need to restart it using the same name you used last time. Do that first then w…

Yes I already did that at the beginning. So my same persistent session is up and running. I already got that heads up from @Paul.Gregory through 21st Century Weather.

OK. Yes well done for following @Paul.Gregory ’s heads up. Have you tried running the suite before? I would perhaps go in and do a rose suite-clean.

Thanks! Yes I did try. But today itself I first clean the suite and then re-run.

Okay, then I will wait and watch. Thanks @cbengel

But just FYI, on that same RAS GUI there were other tasks as well (e.g., ANCIL_ANTS), and those were run successfully through Gadi PBS job submission.

Given the timing and what is going on it is likely to be a Gadi’ type issue. Otherwise, to get feedback on that specific problem you would need to post the contents of the file that can’t be found It might be an intermittent problem. I would wait and try again. If the problem persists then reach…
