AM2 suite failing 'Partial sum file inconsistent'

Hi ACCESS team,

I’m trying to use the AM2 suite u-cz934 to run a 1 year control test, with my own prescribed SSTs.

I updated the SSTs following: um → namelist → Reconfiguration and Ancillary Control → Configure ancils and initialise dump fields → 0fe77425 → ancilfilename → home/565/kt3973/sst_amip_n96_control_updated
Beyond this change, and the start date in the suite configuration, I haven’t changed anything else to run the model.

Now that I am trying to run the model for 1 year from 19000101 I am encountering this error in the job.err log at the atmos stage of the run:

???!!!???!!!???!!!???!!!???!!! ERROR ???!!!???!!!???!!!???!!!???!!!
? Error code: 2
? Error from routine: U_MODEL_4A
? Error message: ACUMPS1: Partial sum file inconsistent. See Output
? Error from processor: 462
? Error number: 39

I haven’t been able to find any documentation online about this, so I’m hoping someone may be able to point me in the right direction to how I can troubleshoot this.

Additional Update:
This was also in my job.out log:

ACUMPS1: Partial sum file inconsistent
PS file holds 166 items and written at STEP 5112
Expected timestep should be < 288
Expected number of items 166
And once again I’m not sure how to troubleshoot the mismatch in timesteps.

Thank you!
Lani.

What change did you make to the start date? Is the initial conditions file consistent with this date (can have a different year, but month/day/time should be the same)?

Hi Scott,
The model basis time used in the run initialisation is 1900-01-01, and the start date in the sst ancil file I created is 1870-01-01 T 00:00.

I’ve also tried in the model basis time:

  • 19000101
  • 19000101T0000
  • 18700101

And received the same error for all three attempts.

I don’t mean to interrupt here, just wanted to say that ACCESS-AM2 and CM2 are not yet supported by ACCESS-NRI. As such I am tagging this outofscope for our ACCESS-NRI support. But it is obviously well suited to the forum and I hope the community can help you out in diagnosing what is happening.
