I just downloaded the CESM2 code on my labtop.
And to run the FHIST compset, and create a case called fhist, run the following commands

cd cime/scripts/
./create_newcase --case fhist --compset FHIST --res f09_f09_mg17

and the results show

ERROR: Could not initialize machine object from /mnt/sdb3/my_cesm_sandbox/cime/config/cesm/machines/config_machines.xml or /home/waccm/.cime/config_machines.xml

how can I figure out this problem ?

You need to define config_machines.xml and place it in either $CESMROOT/cime/config/cesm/machines/ or $HOME/.cime/. I would recommend the former if you expect other users to create cases from your CESM sandbox and the latter if you plan on running cases from multiple versions of CESM on the machine. If neither of those apply, I recommend using $HOME/.cime/ in case you decide to delete CESM at some point in the future and then later want to re-download it and run some more.

To learn more about what is required in the file, see the CIME documentation.

Thanks for reply.
Then should I change the bolded directories in the file of config_machines.xml ?
I'm not familiar with this work....

For example, line 195 to line 242 shows

195 <machine MACH="centos7-linux">

I changed this part using "uname -n"

200 <NODENAME_REGEX>regex.expression.matching.your.machine</NODENAME_REGEX>

to

200 <NODENAME_REGEX>my.machine</NODENAME_REGEX>

then It works

afterthat I executed the ./check_input_data
but another ERRORs come up..

ERROR: module command /usr/bin/modulecmd python load compiler/gnu/7.2.0 mpi/gcc/mpich-3.2 tool/netcdf/4.4.1.1/gcc tool/parallel-netcdf/mpich failed with message:

Do you use modules to maintain different libraries? If so, lines 239 - 242 should include module load statements used to make sure the gnu fortran compiler, an mpi library, netcdf, and pnetcdf are installed (pnetcdf is not strictly necessary)

I also meet the same problem,and it says Could not find machine match for 'log03.hpc.com' or 'log03'
Click to expand...

@ziyucheng and @lvxin -- what version of CESM are you each running? The first response in this thread should fix Could not find machine match errors in CESM 2.0

Hi, I met the same problem. I saw your reply above. But as a beginner here, I don't know how to define the config_machines.xml. It is many lines of code in it. Can anyone tell me how to do that or suggest a link on how to do it?Thanks so much!

Hi, I am new with the cesm build case and compilation procedure. I was able to run create_newcase , but after that , when I enter into case directory and tryed to run build it returns the following error:
b.e20.B1850.f09_g17.01.intel]$ ./case.build

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

Do somebody knows how to solve this issue ?
Thanks in advance
