xmlchange not working on ported CESM2.2.2

[James King]

Hi all,

I have two functioning versions of CESM2 ported to the UK HPC ARCHER2 - CESM2.1.3 and CESM2.2.2. As of today, the xmlchange command has stopped working in 2.2.2, though it still works in 2.1.3: e.g.

2.1.3 example

./xmlquery STOP_N
Results in group run_begin_stop_restart
STOP_N: 1

./xmlchange STOP_N=10
Results in group run_begin_stop_restart
STOP_N: 10
2.2.2 example
./xmlquery STOP_N
Results in group run_begin_stop_restart
STOP_N: 3

./xmlchange STOP_N=10
Results in group run_begin_stop_restart
STOP_N: 3

This is somewhat concerning (this all worked fine last week and I've not made any changes to the model version, nor am I aware of any significant changes to the module versions I load when I run CESM). Has this problem been encountered before and how should I go about fixing it?

Thanks,

James

I looked in the directory in CIME where these scripts are stored:

$CESM/cime/scripts/Tools

and found that in my CESM2.2.2 version the script for xmlchange was blank. I tried replacing it with the script that works in CESM2.1.3, but running this gets an error:

/usr/bin/env: ‘python\r’: No such file or directory
Running 'which python' returns the centrally installed 'cray-python' module
/opt/cray/pe/python/3.9.13.1/bin/python

as expected. I've attached the xmlquery script (which works) and the xmlchange script (which doesn't).

Thanks,

James

In the cesm2.2.2 directory $CESM/cime/ can you run git status? If that file was missing it's probably because the download was interupted or the disk quota was exceeded.

Thanks for the tips - I redownloaded the model and all works now.
