CLM does not write out restart and rest files

[Esther_Bender]

I am using a modified version of CLM5(release-clm5.0 in CESM2.1) (i think) from the NorESM cluster. I just recently had to migrate my modified version to a new supercomputer cluster and after doing that for some reason the simulation does not right out any restart or rest files.

So my question would be what could i check, update, to get it write out the rest and restart files.

It wrote out the land history files without a problem.

We did another test simulation and had the same problem. So it seems to be a more general problem, not just related to that case.

Steps i took to set up:

./create_newcase --machine betzy --case ~/cases/TestIskorasBetzy --res CLM_USRDAT --compset 1850_DATM%GSWP3v1_CLM50%SP_SICE_SOCN_SROF_SGLC_SWAV --run-unsupported --user-mods-dirs ~/InputData/1x1Iskoras_Anom/user_mods/ --project nn2806k --compiler intel --handle-preexisting-dirs r --walltime 02:00:00 -q normal


cp ~/InputData/1x1Iskoras_Anom/user_mods/user_nl_datm_streams ~/cases/TestiskorasBEtzy

I guess I would look at the log files to see what errors might be reported in writing out the restart files. Maybe the 5 year run is not completing successfully. Unless you make some changes to the env_run.xml file, there will only be restart files produced at the end of the run. I assume you are looking in both your archive and run directories for the restart files and not finding any....
You could try modifying the settings to see if intermediate restart files are produced in your 5 year run. E.g., these settings would give you restart files every month:

./xmlchange REST_OPTION=nmonths
./xmlchange REST_N=1
