ERROR: Failed to find or download file inputdata_checksum.dat

[Shruti]

Hello,

I am trying to execute CESM 2.1.2 and facing the above mentioned error.
This occurs in ./case.submit step.

I have modified the config_input.xml file referring the below link.
https://bb.cgd.ucar.edu/cesm/threads/cesm-2-1-1-build-error-lack-of-rpointer-files.4893/
Please find the config_input.xml file attached.

The code works fine generally and the input data gets downloaded.
Could this issue be related to the server from which it is getting downloaded? .

- Also if i need to download data using ./check_input_data --download , at which step do i have to execute it? After ./case.build or where exactly?
- As per my understanding input data changes with compset and resolution values. On what other parameters do the input data change?

Thanks and Regards,
Shruti

input data changes on a wide variety of parameters, way too many to enumerate here.
The cesm will only download the data that you need for a given case, it will reuse data if
it finds it locally rather than downloading it again. As long as you have the data that you need for a case you can safely ignore the error on downloading the inputdata_checksum.dat. check_input_data is run automatically by case.build. If you want to run it manually you should do
./case.setup
./preview_namelists
./check_input_data


You should not need to do these steps manually under normal circumstances.

Hello,

I was trying a fresh download of input data when I faced this issue.
What might be the reason for this error?
Also if I face this error while executing CESM from scratch what should be my go-to solution?

- If I am to share the CESM environment, Is it advisable to keep the required data downloaded while sharing it?
Because the data might be different depending on compsets and resolution?

Thanks and Regards,

Hello, I am facing this issue again.
That some of the files don't get downloaded or is stuck at certain level like mentioned above.

Could this be a server issue?
Should i do changes in config_input.xml file to prioritize svn over ftp?

What does it mean when you run check_input_data and it tells you there are missing files?
Gustavo suggested I switch to a supported case:
create_newcase --res T62_g17 --compset C --case POP_CORE2 --compiler intel

and the compile was successful. I'm getting a number of missing files, starting with

chinook03.rcs.alaska.edu 212% check_input_data

If you run ./check_input_data --download it should download them from the server. case.submit will do the same thing.

Great, success for that phase, thanks!
