Will CESM2.2 be ported to derecho? I've ported CESM to other machines. Any advice about attempting it on my own. I've seen the updates made to CESM2.1 for derecho, which seem like a good starting point.

Thanks! This has worked to the point of getting create_newcase to work. Now it is worth it for us to get some core hours on derecho to compile and test.
For those who need a bit more help on how to get there:
get cesm2.2 from git as instructed in the documentation and then do the following in your directory where you put cesm2.2
./manage_externals/checkout_externals -v -o
cd cime
git checkout remotes/origin/maint-5.8
Then when logged onto derecho run create_newcase with --machine set to derecho

Hi all,
I wanted to update this thread. The above method of 'git checkout remotes/origin/maint-5.8' did not work for me past the create_newcase stage due to incompatibilities with my run configurations. I ended up adding the porting functionality manually by adding the derecho settings to the config_batch.xml, config_compilers.xml, and config_machines.xml scripts. To find the changes, you can look at the git log files in an updated version of cime and search derecho. You should be able to port from there. One issue I ran into was I had to include a header file in one of the c files my case used because the c compiler is different in Cheyenne and Derecho. I have been able to successfully port to derecho and run an CESM case on an SE grid with reanalysis nudging.

Hi Ariel,
Have you ever met the error " /iCESM1_2_0_1_geotrace_n02/models/utils/mct/configure: line 2347: icc: command not found. ?
Is that related to your said "need to include a header file in one of the c files" ?
Thank you!!

Thank you! I will try that.
