./case.submit error in porting cesm2.0.1 on Derecho

[wangly]

Hi,

I am attempting to port CESM2.0.1 to Derecho. I have added the Derecho settings to the 'config_batch.xml', 'config_compilers.xml', and 'config_machines.xml' files in the cime/config/cesm/machines directory, following the CESM2.1.4. I could successfully create a new case and build it, but encountered an error when running './case.submit'.

Here are the error message:

ERROR: Command: 'qsub -q main -l walltime=4:00:00 -A UBUB0005 -v ARGS_FOR_SCRIPT='--resubmit' .case.run' failed with error 'b'qsub: Illegal attribute or resource value select.mpiprocs'' from dir '/glade/work/wangly/cesm2.0.1/cime/scripts/case002'

The official release that you should use is CESM2.1.5
The config_batch.xml from the 2.1 series is not compatible with 2.0.1 - if you insist on porting 2.0.1 you will need to port cime from
python 2 to python 3. The particular issue you are hitting is that the number of tasks is computed as a real value but it should be an
integer. When you solve that one you are going to find several others, I highly encourage you to use cesm2.1.5 instead.

Thank you. We prefer to use 2.0.1 because we have modified many scripts. Do you have any suggestions for porting 2.0.1 directly to Derecho, rather than following 2.1? Alternatively, if the new machine no longer supports 2.0, would it be better to transfer our modifications to the new version of CESM?

Yes, I strongly suggest transferring your modifications to 2.1.5 or perhaps even our 2.3 beta series if this is something that you want in cesm3.
I would be happy to discuss with you if you want to meet next week and tell me more about what you are doing.

Thanks for your suggestion. It would be great to discuss this further with you. I am available next week and would like to meet at your convenience.
