Point-scale simulation with CTSM5.3

[johanna_teresa]

Dear all,

I am currently trying to start using the new CLM version, my code version is ctsm5.3.021 which I have recently ported to our HPC. I am trying to re-create point-scale and regional simulations which have been successful with a previous version, as I would like to use the hillslope hydrology configuration in the future.

I have updated my surface datasets to match the new requirements, and I understand that the previously required domain files are not necessary anymore. I am using the user_nl_datm_streams to define my forcing data. As suggested here, I have set CLM_USRDAT.UNSET:meshfile = none and not specified mesh files in env_run.xml.

The model builds successfully, but then I get this error: "ERROR: (dshr_mod:dshr_mesh_init) ERROR: model_meshfile UNSET does not exist.", which I guessed had to do with the fact that I left ATM_DOMAIN_MESH at UNSET. I tried using ./mesh_maker to create a mesh, but there I get the notification that this is not required for a single-point case.

Any help with this would be much appreciated. I have attached my user_nl_datm_streams file, as well as the log files and my env_run.xml file.

Thanks a lot and best wishes,
Johanna

Could you try setting PTS_LAT and PTS_LON in env_run.xml to your single point coordinates?

Dear Keith,

Thanks a lot for getting back to me.

I tried setting PTS_LAT and PTS_LON, but I couldn't properly see if this solved my initial issue because it revealed a different problem: I had previously set --pecount to 128, but as soon as I set PTS_LAT and PTS_LON this was not accepted anymore. After setting pe count to 1, (either via setting --pecount during the ./case.create step or ./xmlchange NTASK=1) the model would still bild, but fail upon submitting the case. I get 128 PET*.ESMF_LogFiles in my run directory, which I have never seen when running gridded simulations. I copied one of them below. Do you happen to know what the cause for this could be?

Thanks again,
Johanna

Can you try mpi-serial instead of mpich for this single point simulation?

 

[johanna_teresa]

This resulted in the following problem during the ./case.build step:
'ERROR: /users/jmalle/CTSM/libraries/mpi-serial/missing: line 81: aclocal-1.16: command not found'.

I am guessing this is because we only have Automake 1.15 rather than 1.16 on our system. I will look into updating it and let you know if it's successful. In the meantime I will also try and generate a mesh for the single point location following a suggestion from Sean Swenson.

Thanks a lot!
