Help with newly created compset (untested)

[andreasc]

Hi everyone,

I am a new CESM user and I recently started running some experiments with it. I run a ~30 year evaluation run with the untested configuration HIST_CAM60%WCCM_CLM50%SP_CICE%PRES_DOCN%DOM_MOSART_CISM2%NOEVOLVE_SWAV (FWmaHIST; 1 degree resolution and 110L) and stopped the run at year 2010 from which year I'd like to branch out a new chemistry coupled run with 2010 mean climatological fields (e.g. SSTs, CO2), thinking that I'd only have to adapt this configuration to the FW2010climo compset.

For this purpose, I created a new compset (2010_CAM60%WCCM_CLM50%SP_CICE%PRES_DOCN%DOM_MOSART_CISM2%NOEVOLVE_SWAV) and added in all the relevant info in fields like RUN_STARTDATE, RUN_TYPE, RUN_REFCASE, RUN_REFDATE and RUN_REFDIR in components/cam/cime_config/config_compsets.xml (pasted just below). For the RUN_REFDIR, I've made sure that I'm pointing towards the directory of the archived rest files of my FWmaHIST run.

<compset>
<alias>FWmaINT2010</alias>
<lname>2010_CAM60%WCCM_CLM50%SP_CICE%PRES_DOCN%DOM_MOSART_CISM2%NOEVOLVE_SWAV</lname>
</compset>

<value compset="2010_CAM60%WCCM_CLM50%SP_CICE%PRES_DOCN%DOM_MOSART_CISM2%NOEVOLVE_SWAV" grid="a%0.9x1.25">2010-01-01</value>
<value grid="a%0.9x1.25_l%0.9x1.25_oi%0.9x1.25_r%r05_g%gland4_w%null_m%gx1v7" compset="2010_CAM60%WCSC_CLM50%SP_CICE%PRES_DOCN%DOM_MOSART_CISM2%NOEVOLVE_SWAV" >hybrid</value>
<value grid="a%0.9x1.25_l%0.9x1.25_oi%0.9x1.25_r%r05_g%gland4_w%null_m%gx1v7" compset="2010_CAM60%WCCM_CLM50%SP_CICE%PRES_DOCN%DOM_MOSART_CISM2%NOEVOLVE_SWAV">cesm215.FWmaHIST</value>
<value grid="a%0.9x1.25_l%0.9x1.25_oi%0.9x1.25_r%r05_g%gland4_w%null_m%gx1v7" compset="2010_CAM60%WCCM_CLM50%SP_CICE%PRES_DOCN%DOM_MOSART_CISM2%NOEVOLVE_SWAV">2010-01-01</value>
<value grid="a%0.9x1.25_l%0.9x1.25_oi%0.9x1.25_r%r05_g%gland4_w%null_m%gx1v7" compset="2010_CAM60%WCCM_CLM50%SP_CICE%PRES_DOCN%DOM_MOSART_CISM2%NOEVOLVE_SWAV">/glade/derecho/scratch/andreasc/archive/cesm215.FWmaHIST/rest</value>

So, I created a new case with this altered compset before I prepare the forcing files I'd need, just to make sure that the configuration can be setup and built successfully (doing so with ./create_newcase --case FWmaINT2010 --compset FWmaINT2010 --res f09_f09_mg17 --run-unsupported). The setup completes successfully but the building fails almost instantly as I'm getting the following error:
Generating component namelists as part of build
- Prestaging REFCASE (/glade/derecho/scratch/andreasc/archive/cesm215.FWmaHIST/rest) to /glade/derecho/scratch/andreasc/FWmaINT2010/run
ERROR: Reference case directory /glade/derecho/scratch/andreasc/archive/cesm215.FWmaHIST/rest does not contain any rpointer files

I should say that the rest files are there in the set directory but for some reason, it cannot find them. Any help would be much appreciated. My sincerest apologies if I haven't managed to find the correct sub-forum to post this in.

Cheers,
Andreas

I'll defer to any better answers from my colleagues who deal more with restarts than I do... but I think the directory you're pointing to has a lot of subdirectories with restarts, but none in the directory itself. Since your run date looks to be 2010-01-01, could you try:

./xmlchange RUN_REFDIR=/glade/derecho/scratch/andreasc/archive/cesm215.FWmaHIST/rest/2010-01-01-00000

That directory has the rpointer files for that case & date.

Thanks very much Brian, that seems to have done the trick. I guess I could also change it in the config_compsets.xml file directly so I don't have to run ./xmlchange.
