Moving from Cori to Nersc, case build failed.

[CaliFornia]

Hi everyone,

I was running simulations with E3SM on Cori and now I have to move to Nersc with the same codes and scripts.

What I did:
Edited some necessary vars such as machine name, case name and file paths in the run script.sh.

Problem after executing the run script:
----- Starting create_newcase -----
No error was found
----- Starting case_setup -----
Configuring E3SM to use the COSP simulator
Successfully cleaned env_mach_specific.xml
ERROR: module command /usr/share/lmod/lmod/libexec/lmod python load PrgEnv-gnu/8.2.0 gcc/10.3.0 craype-accel-host cray-libsci craype cray-mpich/8.1.13 cray-hdf5-parallel/1.12.1.1 cray-netcdf-hdf5parallel/4.8.1.1 cray-parallel-netcdf/1.12.2.1 cmake/3.22.0 failed with message:

Try: "module spider cray-mpich/8.1.13 PrgEnv-gnu/8.2.0" to see how to load the
module(s).

Does anyone know how to solve this issue? Thank you very much!

I edited /cime_config/machines/config_machines.xml based on the error message, and the command "module spider xxxx" sometimes shows several different versions of the software. Now the model can run, but how do I know if I am using the right version? Does it matter? Thank you.
