[MITgcm-support] [MITgcm Manual] section 6.15 NetCDF I/O Integration: MNC

Hi there,

I am currently working on completion of the biogeochemistry tutorial (http://mitgcm.org/public/r2_manual/latest/online_documents/node155.html) and am amending the path names for the "c62g" release of the MITgcm. I have built a test script in order to submit the job to a Sun Grid Engine running on the parallel computing cluster here at my University. Every time the job is completed I get an output file from the system containing the following text:

***WARNING*** PACKAGES_CHECK: useMNC is TRUE
***WARNING*** but pkg/mnc has not been compiled (#undef ALLOW_MNC)
STOP NORMAL END statement executed

This is irrespective of whether the MITgcm is compiled with the -enable=mnc or -disable=mnc switches. I have also commented out #mnc in the "packages.conf" file within the "/MITgcm_c62g/verification/tutorial_dic_adjoffline/code_ad" directory. 

I imagine I would like to use MNC since I am under the impression that using NetCDF is likely to make the process of using the model output quicker. Can you tell me how I can get rid of that warning and exactly what I should in order to get the MITgcm running as I would like.

Regards,
Phil
