CICE6 at 1/12 degree

[hCk]

Has anyone run CICE6 at 1/12 deg and are there any issue or library requirements for reading & writing history and restart files?

We have run CICE6 at 1/12 degree resolution and have not had any issues with library requirements like NetCDF. In this case make sure in your ice_in file you have lcdf64 = .true. to write large NetCDF files. Since this is a large domain, make sure you are running with enough compute nodes/processors so you have adequate memory for your run. That will vary by machine, but somewhere around 200 processors should be sufficient.

We also running CICE6 coupled with POP2.1 within RASM frame with 1/12 degree and found no problems. Our outputs both history and restarts are in NetCDF format. History monthly files are creating with setting:
hist_avg = .true.
histfreq = 'm','d','h','x','x'
histfreq_n = 1,0,0,0,0

and formats:
lcdf64 = .true.
restart_format = 'pio'

Thanks for the replies.

I am trying to convert 1/12-th SIS2 restart to 1/12-th CICE5 using NCL tool but it keeps complaining as follows:
"NetCDF: One or more variable sizes violate format constraints".
I used the setfileoption for NCL "LargeFile" and "64BitOffset" but it still did not work.

Any comments or suggestions will be appreciated.

Make sure you have all needed variables to start CICE from restart. Note the necessary information may vary on chosen CICE's options for instance EVP vs EAP rheology restarts are different.
