Postproc failing

Unified Model
,
1

Hello,

I’m trying to run a suite (u-cf771) on ARCHER2 that I have copied from a suite that was previously running on NEXCS. The postproc is failing due to “Bad optional configuration key(s): archer2”. Could you advise?

Thank you!
Lauren

Hi Lauren,

Your suite is set up with an optional configuration override file for postprocessing settings. See ~/roses/u-cf771/app/postproc/opt/rose-app-archer.conf. You will need to create a similar file called rose-app-archer2.conf. You will then need to change the means_cmd to:

means_cmd=ncra --64bit_offset -O

Regards,
Ros.

Hi Ros,

Thank you! The postproc has now succeeded except for cice due to a missing ncrcat path. What should this be?

Thank you,
Lauren

Hi Lauren,

The path for ncrcat should be blank as it is added into the environment when the nco module is loaded. You’ve got /work/y07/shared/umshared/nemo/nco/nco-4.4.7/bin in the job.err file. I’m not sure why that is as I can’t see your /work directory on ARCHER2. It’s obviously not picking up the override correctly. Setting ncrcat_path to blank in the GUI will probably fix it, but you may get other problems if that override isn’t working.

If you give me read access to your directories on ARCHER2 I can take a look.

chmod -R g+rX /home/n02/n02/<your-username>
chmod -R g+rX /work/n02/n02/<your-username>

Cheers,
Ros.

Hi Lauren,

I’m rather confused as to why you had that postproc archer2 opt config error at the beginning now because it’s not using an optional override file for postproc - the settings in the namelist over on ARCHER2 are the ones in the GUI hence the path issue. Change the following two variables in the GUI and hopefully that will fix the problem.

  • means_cmd to ncra --64bit_offset -O and
  • ncrcat_path to blank.

Regards,
Ros.

Hi Ros,

That’s sorted it, thanks very much!
