running UM on ARCHER

Reported by: anmcr Owned by: um_support
Component: UM Model Keywords: running UM
Cc: Platform: ARCHER
UM Version: 7.3


Good morning,

I submitted a vn7.3 UM job to ARCHER yesterday for the first time (identifier xhldo).

However, it has been stuck in the queue for almost 24 hours.

I believe I have made the correct changes for running on ARCHER
(i.e. as suggested by

I would be very grateful for any help.

Best wishes,

Please make your ARCHER home and work spaces readable.

Dear Grenville,

I've changed the permissions.

I also raised a ticket yesterday that I had run out of disk space on ARCHER. So perhaps this is connected? But the fact the job was simply queuing for such a length of time made me suspect something else was happening.

Thanks for your help,

Please delete the queued job and resubmit.

Hi Grenville,

I deleted the job and resubmitted. However, I get a 'model build: failed' error during the compilation (/home/n02/n02/anmcr/output). I looked through the output file but was unable to identify the problem.

Hi Grenville,

I looked through some of the other jobs submitted to ARCHER and a number of them had included the hand edit '~ros/umui_jobs/hand_edits/archer/cce-7.3.ed'. It's not much better than tinkering, however I tried to run the model with this included. However, now I got a 'permission denied' error when I tried to submit. I also get the same error with /work/n02/n02/anmcr on ARCHER. Not quite sure why …

Hi Andrew,

You could switch off the hand edit


this might be confusing things.



comment:7 Changed 7 years ago by ros

Hi Andrew,

For some reason your job is trying to link to the wrong version of GCOM. I've investigate and get back to you.


comment:8 Changed 7 years ago by ros

Hi Andrew,

Sorry, I just realised I mis-read one of your previous emails and read override file for hand-edit! :-(

You need to change the User Override files from




And similarly change the File override to archer_cce_7.3_file

You don't need my hand-edit ~ros/umui_jobs/hand_edits/archer/cce-7.3.ed (In actual fact I deleted it a while ago hence the permission denied that you got).

Hopefully that will fix your problem.

Dear Ros and Willie,

Thank you for your help. I've made some progress. The changes I made were

1) Changed the User machine overrides to '/home/umui/overrides/archer_cce_7.3_machine'.

However, what do I do regarding the 'User file overrides' which are still being used (/home/umui/overrides/hector_cce_7.3_file and /home/ukca/comp_overrides_hector_cce_7.3_asad_chem_diags)?

2) Removed the hand edit '~ros/HadGEM3-A/vn7.3/HGPKG1/ibm_modules.scr'

3) Removed the hand edit '~ros/umui_jobs/hand_edits/archer/cce-7.3.ed'

However, the reconfiguration fails with the error:

User Prognostic File does not exist.
File : /work/n02/n02/annette/hadgem3/ancil/land/ORCA2_N48/topog_index_mean ERROR!!! in reconfiguration in routine Rcf_Create_Dump

This file/path is on HECToR. Unfortunately it must be given by its full path as I have changed all the environment variables to point to ARCHER. Could you please tell me which UMUI panel this could be found, so that I can point it to a file on ARCHER?

Thank you,

Hi Andrew,

  • You need to change the file override to archer_cce_7.3_file
  • Leave the /home/ukca/comp_overides/hector_cce_7.3_asad_chem_diags as is. We are still using the same compiler and having taken a look at this file it will work just fine.
  • The paths to the user prognostic files are set in UMUI window Atmos → STASH → Initialisation of User Prognostics

Dear Ros,

I've made these changes. The reconfiguration seems successful now. However, when I run the model executable it runs for a few time steps and then fails with the error below. Unfortunately I was unable to get to the bottom of it. Can you able to advise?

Many thanks,


UM Executable : /work/n02/n02/anmcr/xhldo/bin/xhldo.exe

sys-2 : UNRECOVERABLE error on system request

No such file or directory

Encountered during an OPEN of unit 99
Fortran unit 99 is not connected

comment:12 Changed 7 years ago by anmcr

Hi again,

I don't know what file 'unit 99' refers to. I've seem similar errors in ticket #771 and #778. Check setup is complaining about broken codes in the USERLIST_A (user-stashmaster files), which #778 suggests could be relevant.


comment:13 Changed 7 years ago by anmcr

Hi again,

The reference to 'USERLIST_A' when Check Setup is run is discussed in #957. Willie said there that it was not an error, simply a nuisance.

Unfortunately, I'm still no closer to identifying what file 'unit 90' refers to.


comment:14 Changed 7 years ago by anmcr

Hi again,

I differenced my job (xhldo) with a standard UKCA job on ARCHER (xfvgd).

The only significant differences that I could see were:

1) hand edits ('N' in xhldo and 'Y' in xfvgd)


2) branches (both 'N' in xhldo and 'Y' in xfvgd)


I changed these to 'Y' but the error still remains, so I guess whatever file 99 is it is on HECToR but has not been copied to ARCHER.



comment:15 Changed 7 years ago by anmcr

I think this is the problem.

A file with 'unit 99' is being opened in ukca_read_era.F90.

It's location is on HECToR at /work/n02/n02/jmk64/tbias_data/era_2000.asc.

This is in the branch fcm:um_br/dev/jmk64/VN7.3_UKCA_CheM_PSC_production_run/src.


comment:16 Changed 7 years ago by ros

Hi Andrew,

Sounds like you have tracked down the problem. I was just beginning to investigate. James doesn't yet have an account on ARCHER as far as I can tell, so you will have to copy over the era_2000.asc file to ARCHER and then create yourself a new branch. Merge James' changes in and then modify the path to this file. If you need any help with this let me know.


comment:17 Changed 7 years ago by anmcr

Hi Ros,

I've got this to run now, so please close this ticket.

Thanks very much for your help.


comment:18 Changed 7 years ago by ros

  • Component changed from Other to UM Model
  • Resolution set to fixed
  • Status changed from new to closed

comment:19 Changed 7 years ago by annette

Hi Andrew and Ros,

Just to say that everything that was under /work/n02/n02/annette/hadgem3/ on HECToR is now in the same location on Archer.
