ARCHER2 dump file error

1

Hi there,

I tried to run a suite u-dw252 with an initial file dw230a.da20121001_00 under /home/n02/n02/emxin/archive, however, the model crashed with an error - trying to find a different dump file to start:

Error message: Failed to open file /work/n02/n02/emxin/cylc-run/u-dw252/share/data/dw252a.ainitial

in rose-suite.conf, I see

AINITIAL_FILE=‘dw230a.da20121001_00’

ARCHER2_AINITIAL_DIR=‘/home/n02/n02/emxin/archive’

In archer2.rc, I see:

{% set AINITIAL = ARCHER2_AINITIAL_DIR + ‘/’ + AINITIAL_FILE %}

They all look fine to me. Where I should check?

BTW, I got the same problem when using /work/n02/n02/emxin/archive instead of /home/n02/02/archive.

You need to set the namelist variable ainitial (currently ainitial=‘$ROSE_DATA/${RUNID}a.ainitial’)

Note, compute nodes can not see /home. Start files need to be on /work.

Hi Grenvile,

I manually replaced the old ainitial link on the suite namelist with “archer2_ainitial_dir+‘/’+ainitial_file” but got error:

Error code: 1
? Error from routine: io:file_open
? Error message: Failed to open file archer2_ainitial_dir+‘/’+ainitial_file
? Error from processor: 0
? Error number: 4

It seems I did not make the change to “ainitial” correctly. Please let me know how or where I should make the change. Thanks.

You could simply set ainitial to /work/n02/n02/emxin/archive/dw230a.da20130901_00

Hi Grenville,

It seems the original ainitial=‘$ROSE_DATA/${RUNID}a.ainitial’) is working fine. The new issue is that my suite was trying to find ancillary files for CHI and DMS, but failed (though they worked well before). Those files were locatedat: /work/n02/n02/waltonj/ancil/MEDUSA/clims/by791/CHL/CHL_clim_by791_1979_2014_n96.anc

/work/n02/n02/waltonj/ancil/MEDUSA/clims/by791/DMS/DMS_clim_by791_1979_2014_n96.anc

However, I could not accessthem now:

Ancillary Files to be opened :

Ancil filename : /work/n02/n02/waltonj/ancil/MEDUSA/clims/by791/CHL/CHL_clim_by791_1979_2014_n96.anc

Ancillary File does not exist.

File : /work/n02/n02/waltonj/ancil/MEDUSA/clims/by791/CHL/CHL_clim_by791_1979_2014_n96.anc

Ancil filename : /work/n02/n02/waltonj/ancil/MEDUSA/clims/by791/DMS/DMS_clim_by791_1979_2014_n96.anc

Ancillary File does not exist.

File : /work/n02/n02/waltonj/ancil/MEDUSA/clims/by791/DMS/DMS_clim_by791_1979_2014_n96.anc

I noticed that Graham recently posted a message regarding the updates on ancillary files for nudged jobs, including CHI and DMS: https://cms-helpdesk.ncas.ac.uk/t/gotchas-within-converting-to-post-2015-for-nudged-monsoon3-v13-9-ukesm1-1-amip-runs/1975/2

Where he mentioned updated ancillary files inclduing CHI and DMS, however, they are on Monsoon, e.g.

3. Ocean chlorophyll: file = CHL_clim_by791_1979_2014_n96.anc

Dir = /projects/ukesm/jeremy.walton.mon/ancil/MEDUSA/clims/by791/CHL/

5. Ocean DMS: file = DMS_clim_by791_1979_2014_n96.anc

Dir = /projects/ukesm/jeremy.walton.mon/ancil/MEDUSA/clims/by791/DMS/

Could you help copy them to ARCHER2? or let me know how to get them downloaded to ARCHER2.

Thanks.

Best,

Xin

Hi Xin,

Apologies I was archiving some old accounts, and didn’t realise that there were UKESM ancillaries under the waltonj work space. I have restored access, so you should be able to see the files again now.
