Running CESM on Derecho

Hello,

I am having some trouble running CESM on Derecho and could use some advice.
So far, I have done the following in my home directory

git clone GitHub - ESCOMP/CESM: The Community Earth System Model my_cesm_sandbox
cd my_cesm_sandbox
git checkout cesm2_3_beta15
./manage_externals/checkout_externals
cd cime/scripts
./create_test

I then received the following error message

ERROR: Could not initialize machine object from /glade/u/home/cpersch/my_cesm_sandbox/ccs_config/machines/config_machines.xml. This machine is not available for the target CIME_MODEL.

I've also tried the script 'create_newcase' a couple of times with different compsets and grids, always specifying --machine derecho. I then will get an output as follows

cime/scripts> ./create_newcase --case ./test --compset B1850 --res T31_g37 --mach derecho
Compset longname is 1850_CAM60_CLM50%BGC-CROP_CICE_POP2%ECO_MOSART_CISM2%GRIS-NOEVOLVE_WW3_BGC%BDRD
Compset specification file is /glade/u/home/cpersch/my_cesm_sandbox/cime_config/config_compsets.xml

OCN component is POP2 Ecosystem

GLC component is cism2:include non-evolving Greenland Ice Sheet:

Compset specific settings: name is RUN_STARTDATE and value is 0001-01-01

Any advice would be appreciated!
Thanks,
Cole

Hi Cole,

Is there any reason you need to use the beta15 tag specifically? If not then I might recommend using the latest alpha tag (cesm2_3_alpha16g) instead, as that tag does have a defined derecho configuration option.

Of course if for some reason the latest tag doesn't work for you then please let me know.

Thanks, and have a great day!

Hi Jesse,

Thank you for the information! I just met the same issue when using CESM2.2.0. But as instructed on the tutorial, git tag --list 'release-cesm*' does not show anything about cesm2.3. Is the cesm2_3_alpha16g an officially released version that we can trust and based on which we can publish papers?

Thank you.

The cesm2_3_alpha16g is not a released version but 'taged'. There are 'releases' and 'tags': Tags · ESCOMP/CESM.

You can run:
>git clone -b cesm2_3_alpha16g GitHub - ESCOMP/CESM: The Community Earth System Model my_cesm_sandbox

to download the source code.

Hi Everyone,
Could you please suggest more regarding the following information from UCAR help
I am using CAM 6.3 of CESM2
Hello DK,

You are trying to submit a job to the 'regular' queue, but there is no 'regular' queue on Derecho. It's likely that you are using a version of CESM that is not ported to Derecho. I would recommend running a version of the model that has been ported to Derecho, as porting it yourself can be difficult. You should consult CESM support at the CESM Bulletin Board for details, but I believe they have several ported versions available.

Hi Dharmendra,

Can you try running on Derecho using CESM version 2.1.5? That is the official version of CESM2.1 that has Derecho support. You should be able to acquire the source code via the following commands:

Code: 
git clone https://github.com/ESCOMP/CESM.git
cd CESM
git checkout release-cesm2.1.5
./manage_externals/checkout_externals

Once you have this version of the model you should be able to specify -mach derecho when creating a new case and have it work as expected. Of course if that doesn't work for you please let us know.

Thanks, and have a great day!

Jesse
