cesm2_3_beta08 Porting error

[jhPark]

Hello.

I am trying to port cesm2_3_beta08 to implement CAM6-MOM6 coupled model.

config_machines.xml, config_batch.xml, and config_compilers.xml that worked in CESM 2.2 version were used for porting cesm2_3_beta08, but the following error occurred during ./case.setup. Previous CESM 2.2 versions worked fine.

ERROR: Could not initialize machine object from /lustre/cesm2/CESM_MOM6/ccs_config/machines/config_machines.xml. This machine is not available for the target CIME_MODEL.

To solve this error, I tried following the other advice in the CESM forum, but it still doesn't run with another error.

If anyone knows more about this, any help would be greatly appreciated.

Thanks.

config_machines.xml requires variables to be in a specific order. This order is listed in file /lustre/cesm2/CESM_MOM6/cime/config/xml_schemas/config_machines.xsd
In this case the error appears to be that the NODENAME_REGEX line should precede the OS line.

Thank you for your help.

I'll try this and leave a reply back.
