NetCDF large file option is ignored for history files #22

Closed nichannah closed 4 years ago

nichannah commented 5 years ago

CICE has a namelist option to turn on netcdf large file support. This flag is only applied to restarts not to diagnostic output.

We have been getting this error when writing output:

ice: Error in nf90_enddef: NetCDF: One or more variable sizes violate format constraints

This error usually happens when the file size is too big for the NetCDF format file type. We hope that by enabling large file support on the diagnostic output this will go away.

If files are getting that large should we look into adding support for netCDF4 with compression?

russfiedler commented 5 years ago

Any reason for not enabling netCDF4 rather than large file support? Kills 2 birds with one stone.

russfiedler commented 5 years ago

Great minds thinks alike!

nichannah commented 5 years ago

OK, good idea. I'll leave the issue open for that purpose.

nichannah commented 4 years ago

The large file support option has been removed and netcdf4 compression is now supported.
