UP_BOUND : Reached end of atmosphere LBC file

Reported by: ggxmy Owned by: um_support
Priority: highest Component: UM Model

Platform: ARCHER UM Version: 8.2


My UM vn8.2 limited area job, tewnf, ran for 30 days but crashed just before it finishes 1 month simulation. /home/n02/n02/masara/output/tewnf000.tewnf.d18169.t154803.leave.20180623-003207 has these messages near the top;

similar messages are near the bottom as well, and they are after these lines;

So the problem might have happened while or after process 0 tried to update lateral boundary condition? Please can I have advice on this?

You have run out of lbcs - you only have lbcs til 2011/05/31 - you need to extend the time over which lbcs are available.


comment:2 Changed 3 weeks ago by grenville

Have you changed the UMUI set up since submitting the job - tewnf says to run for 1 day and 1hr, but it's run for 1 month?

comment:3 Changed 3 weeks ago by ggxmy

Hi Grenville,

How do I extend the time over which lbcs are available?

I can't remember for sure, but I think I had submitted the job for 1 day and because it ran OK, I made the run length longer on ARCHER side by modifying CNTLALL, SUBMIT, umuisubmit_run. Should I have set the run length on UMUI rather than on ARCHER? Or is there anything else I need to do on ARCHER side?


comment:4 Changed 3 weeks ago by willie

Hi Masaru,

The original job was designed to run for 153 days in 30 day chunks with an LBC file for each chunk. The bottom script (Model Selection → Input/Output Control … → Scripts inserts …) handles the transition from one LBC to another. Looking back at the original xlhub it was taking nearly 42 hours in the ARCHER long queue to do the 30 days.


comment:5 Changed 3 weeks ago by ggxmy

Hi Willie,

Thanks for the note. It takes only about 24 hours to run for 30 days now. But I submit the job to the long queue anyway.

The UMUI page you point to shows dummy_script and lbc_update_v3.scr, and I have both of these in my /work/n02/n02/masara/ directory. lbc_update_v3.scr contains lines;


and these files are contained in /work/n02/n02/masara/xklhf_makebc/ . I'm not sure if the model knows where to look for these files, but when I didn't have xklhf_makebc directory it gave me an error for that. So I guess it knows. So things look OK. Can you think of anything else I should do or check?


comment:6 Changed 3 weeks ago by willie

Hi Masaru,

The LBC update script is custom designed for the SWAMMA 4km runs as originally envisaged. If you are just doing a repeat, then it should work without problems. If you are modifying the run lengths then the update scripts might not be appropriate.

What are you trying to do?


comment:7 Changed 3 weeks ago by ggxmy

HI Willie,

I just wanted to run the job for 5 months but it failed at day 30 (0530). Outputs for that date has no value. I think in this case I submitted the run for 1 month and 1 day. (I usually do this to make sure to get monthly mean outputs. In this case though I haven't requested any monthly mean fields so doing this might not have any benefit.) Should I have stuck on 30 days? Could I use automatic resubmission after the initial 30 days?

If possible I want to run for 153 days as 4 40-day runs instead of 6 30-day runs and that will save queuing time. Can't it be done simply by changing resubmission pattern?


comment:8 Changed 3 weeks ago by willie

Hi Masaru,

You should stick to 30 days. I didn't have a problem with the monthly means in the past. With hindsight, I should have made the LBCs a bit longer for doing short runs.

So do a 30 day NRUN, then switch reconfiguration off and do the continuation run. Barring ARCHER issues, it should run straight through.


comment:9 Changed 2 weeks ago by ggxmy

Hi Willie,

I tried to run a CRUN hoping it starts from where it crashed, but it didn't work. I got this;

? Error in routine: inbounda
? Error Code:   101
? Error Message:  Boundary data starts after start of current boundary data interval
? Error generated from processor:     0

Do I need to redo the first month as NRUN?


comment:10 Changed 2 weeks ago by willie

Hi Masaru,

The model is now in the wrong state, so you have to do the NRUN from the start for exactly 30 days.


comment:11 Changed 2 weeks ago by ggxmy

OK. Thanks.

So I ran tewnh for the first 30 days as NRUN again. That seemed successful and was completed yesterday. Then, should I go back to UMUI and submit the job as CRUN for another 30 days? That's what I did, but by checking the outputs I was a bit confused.

at first I thought the job had run for May again but it actually produced outputs for June. Getting outputs for 0530 after 0629 looks strange but is it OK?

The run stopped here successfully, but automatic resubmission failed and left the same message as above;

? Error in routine: inbounda
? Error Code:   102
? Error Message:  Boundary data ends before end of current boundary data interval
? Error generated from processor:     0

Is this a problem or not? Do I just need to go back to UMUI and submit CRUN again? Do I need to repeat this for every 30 days of simulation?


comment:12 Changed 2 weeks ago by ggxmy

Oh no! I resubmitted tewnh as CRUN from UMUI but it crashed leaving the same message as above. Maybe I simply don't know how to submit CRUN because I have never done that in the last few years. Please could I have advice?

Thank you.

comment:13 Changed 2 weeks ago by willie

Hi Masaru,

It looks like the the model is in a confused state. You should delete the working directory and do a NRUN again.

To do an NRUN, you need to switch off automatic resubmission (in the Resubmission pattern panel) and switch reconfiguration on.

To do a CRUN, when the NRUN is complete, you need to switch off reconfiguration and switch on automatic resubmission to allow the run to be continued. It will then run repeatedly until the end date (CRUN).


comment:14 Changed 2 weeks ago by ggxmy

Hi Willie,

By working directory did you mean ARCHER:/work/n02/n02/masara/um/tewnh ? Should I delete this directory?


comment:15 Changed 2 weeks ago by willie

Hi Masuaru,
Yes, the idea is to delete any incorrect history and give it a fresh start.

comment:16 Changed 2 weeks ago by ggxmy

Thank you, Willie.

Because transferring the outputs for June was taking a while, I copied the job to a different jobid (tewnl) and submitted. Let's see how it goes.

In the meanwhile I kept tewnf going only hoping to get results for June. It is exactly in the same situation as tewnh and so I had expected it would crash at the end of June. But it actually seems to be resubmitted OK and now simulating the third month (July). Lucky isn't it?


comment:17 Changed 9 days ago by ggxmy

I was waiting for a reply to the comment I made yesterday but my comment itself does not seem to be here… It might not have gone through. The situation remains the same today.

I'm still struggling with this problem. Automatic resubmission fails with tewnh and another job again and again. I gave it another try after deleting the entire directories archer:/work/n02/n02/masara/um/tewnh and puma:/home/ggxmy/um/um_extracts/tewnh . At this point it is still running for NRUN so I will have to wait another day or two.

ON the other hand, as I mentioned, tewnf was going OK up until 0927 where the final resubmission failed. It left the same error message as above (error code = 102). I manually resubmitted it as a CRUN from UMUI but it didn't work and left the same error again. Could you please help me for tewnf now?

Thank you.

comment:18 Changed 9 days ago by ggxmy

A couple of NRUNs have finished now. I was expecting if they fail they would do so at the end of the first CRUN (end of June) and wasn't worrying about NRUN. But actually I found these NRUNs had not finished without a problem… All of tewnh, tewnm and tewnn crashed at their 30th day of simulation leaving the same error at the top of this ticket (Error Code: 11). This is really a shocking result to me… Can you help me please?

comment:20 Changed 9 days ago by willie

Hi Masaru,

This ticket is really confusing now. You are running too many models tewnf,h,l,m and n for me to see what's going on.

I think tewnl was the one that you ran from the start with 30 day CRUNs. Is this still working?

All the others I think are irrelevant - there being no difference between them except how they were initiated. It is really important if a run fails that you do not resubmit it without first finding out the reason for the failure. Just resubmitting will fail and muddy the waters.


comment:21 Changed 9 days ago by ggxmy

Even though I ran a few jobs, all other than tewnf have encountered the same problem. The problem with tewnf is basically the same also and only happened at a different stage. If the problem with tewnh is resolved, then the problem for all other jobs will likely be resolved. So the situation may appear to be complicated at the first glance, it is actually not.

Because I deleted all relevant directories, I thought they were quite likely to run, and I expected that all jobs would run for at least 60 days. If they run for 60 days I can make some progress in scientific analyses. I have spent too much time on trials and errors in running the UM jobs and I have no time to be waiting until I see tewnh runs OK before I submit other jobs. That's why I ran multiple jobs at the same time.

The ticket is very long now but message is simple. I'm still getting errors 11, 101 and 102. The job I want to be checked is tewnh. Can you do that?


comment:22 Changed 8 days ago by willie

Hi Masaru,

I have taken a copy of your tewnh job and will try to run it for 35 days (see my job xobtc).

As I was doing this I realised the instructions I gave for NRUNS/CRUNS were not complete. I am sorry about that.

It turns out that there is a key switch on the Compilation and Run Options → Compile and run options for Atmosphere page.

To do an NRUN, deselect "run the configuration". This activates the "Type of Run" section. Then tick NRUN. You can then reselect "run the configuration". Then Save, Process and Submit.

To do a CRUN, deselect "run the reconfiguration" and then select CRUN. Then Save, Process and Submit.

So on the Input/Output? Control and Resources → Re-submission page, the "automatic resubmission" button should be selected throughout NRUNS and CRUNS.

To run for 35 days, set this on the Start date and run length options page. This never changes.

I expect xobtc to complete in a couple of days.

Once again, I am sorry for confusing you.

One other thing I noticed was that the Ancil Headers had been set to 100,000 (In the Ancillary → Infile related options → Header record sizes page). In my run I have changed this back to 50,000 as it was in xlhub.


comment:23 Changed 8 days ago by ggxmy

Thanks, Willie. Okay so tewnf might have happened to run because I had submitted it before I followed your previous instruction. I just resubmitted tewnh. I hope it runs OK this time. Fingers crossed.


comment:24 Changed 6 days ago by willie

Hi Masaru,

The job xobtc has completed the 35 days successfully: one NRUN followed by one CRUN. See the leave files at /home/n02/n02/wmcginty/output/xobtc*.

There are some netCDF errors reported but these can be ignored since the variables in question don't need to be output.


comment:25 Changed 6 days ago by ggxmy

Thanks, Willie. If 30 day simulation finishes successfully, the next hurdle is the first automatic resubmission which takes place after finishing the day 60 and before starting the day 61. That is when I got errors 101 above.

My tewnh also finished the 30 day simulation successfully, but CRUN might have been somehow killed without leaving any output at all…

tewnh.fort6.pe0 has the newest time stamp of all pe outputs and it appears to me to finish abruptly and I don't see any suggestion of a problem. Its last few lines are like this;

 Minimum theta level 1 for timestep  22442
            This timestep           This run
   Min theta1     proc      Min theta1 timestep

   0.330E+01  30   43  0.507E+01   18 19405

I checked a couple of other pe outputs but they look similar. It seems to have been simulating the day 0608 that time. I have never seen anything like this. Are you aware of any disruption on ARCHER this morning around 3? doesn't show anything to me.

Should I resubmit the same CRUN? I'll try it anyway.


comment:26 Changed 6 days ago by ggxmy

this may be the problem…

I'll delete some of the files before resubmitting the job.

comment:27 Changed 6 days ago by ggxmy

I never had a chance to ask this. Is it OK to delete /work/n02/n02/masara/um/[jobid]/core.* files? I think long time ago I saw somebody using the core files but I've never used them myself or never learnt how to use them. Also, is it OK to delete [jobid]a.p?2011mmdd(_hh) files (?=a-j)? I know I can delete many of the .da files although I want to keep some of them.


comment:28 Changed 3 days ago by ggxmy

tewnh crashed in day 0629 leaving the same error as the top of this ticket (error code 11)… The situation is very similar to before if not exactly the same. I got the same error at a bit different timing. It crashed at the end of first CRUN period instead of the end of the NRUN period.


comment:29 Changed 19 hours ago by ggxmy

Willie, can you test your job for another two month as CRUN with automatic resubmission turned on?
