Hi, everyone, I am trying to porting the CESM2 in my hpc. A error occured when ./create_newcase --case mycase --compset X --res f19_g16. Here is the detail:

Attach are the config_machines.xml and the config_compilers.xml in my $HOME/.cime.
I have searched in the forum but still not work, what should I do to solve the question?
Thanks very much!

I think that you need to remove the <default_run_suffix> section from the end of your config_machines.xml file. And your config_compilers.xml should have only a section for your particular machine (MACH="atmoce-epyc01"). These files are appended to the default files found in cime/config/cesm/machines and should not repeat any of the sections found therein.

Thanks! I have solved the error!
A new error occur when I run ./case.build.

In the shell:

ERROR: BUILD FAIL: buildexe failed, cat /raid61/mczhao/scratch/mycase1/bld/cesm.bldlog.210305-134738

And the cesm.bldlog.210305-134738 file shows that:

hi! have you solved this problem?
 
Hello, I am having the same problem. I am trying to create a new case on a rocky linux 8.5 machine. I've created an anaconda environment and installed cesm and all its systems prerequisites inside that environment.

Below there is the output I get. I left only the sections from my particular machine in the config files (attached). I don't know elsewhere to look.
The config files are in $CESMROOT/cime/config/cesm/machines

Any help will be much appreciated!

Do you have anything in directory ~/.cime? If so try removing it.
Try the create_newcase command again with the --debug option.
 
Hi Jim,
I've been seeing this .cime directory, which seems like a hidden directory, but I don't have it, as I show below:
Or am I looking for the wrong thing??

(cesm) [numa19@ire0233 cesm2.1.3]$ pwd
/home/numa19/cesm/cesm2.1.3
(cesm) [numa19@ire0233 cesm2.1.3]$ ls -a
. ChangeLog_template components doc .github manage_externals
.. cime Copyright Externals.cfg .gitignore mpi_test
ChangeLog cime_config describe_version .git LICENSE.txt README.rst
(cesm) [numa19@ire0233 cesm2.1.3]$ cd cime
(cesm) [numa19@ire0233 cime]$ ls -a

.. CMakeLists.txt doc .gitignore .nojekyll src utils
ChangeLog config .git index.html README.md tools
(cesm) [numa19@ire0233 cime]$

Before creating a new case, I also tried to run the scripts_regression_test.py to validate porting and the same error (Expected one child) returns.

Finnaly, I tried create_newcase with the --debug option, below. It seems like it get stuck. Attached is the output.

(cesm) [numa19@ire0233 scripts]$ ./create_newcase --case /disco2/cesm/cases/b.day1.0 --res f19_g17 --compset B1850 --debug > out2.txt

Thank you so much for the help!

Sorry for not being complete. The directory would be $HOME/.cime but if you don't know about it you probably don't have it.
As for using the debug option, it's dropping you into the python debugger. Run it again and this time type 'where', this should show
what the problem is.
 
Hi Jim!

I did what you suggested and here is the result:

Okay I see it now, when you striped the config_machines.xml file you took out too much. At the end of the file after </machine> but before </config_machines> you should have
Code:
  <default_run_suffix>
    <default_run_exe>${EXEROOT}/cesm.exe </default_run_exe>
    <default_run_misc_suffix> >> cesm.log.$LID 2>&amp;1 </default_run_misc_suffix>
  </default_run_suffix>
 
I did take too much from the config_machines.xml!!

I put the missing code and it created the case successfully!
I also ran case.setup and I am running cesm.build

But then, I tried to run the scripts_regression_test.py and I still get FAILs. The output file is attached.

(cesm) [numa19@ire0233 tests]$ python scripts_regression_tests.py

----------------------------------------------------------------------
Ran 361 tests in 461.567s

FAILED (failures=77, errors=5, skipped=17)

If you want to be able to run scripts_regression_tests.py then you need to follow the porting instructions.
In particular you should not remove all of the provided code from the xml files, you should simply append your
new machine. The output you provided from scripts_regression_tests.py is incomplete - you need to capture stderr as well as stdout.
