NetCDF and Related Module Changes
With the migration of the Halstead, Snyder, and Rice clusters to CentOS7, the configuration of the NetCDF related modules has changed. You no longer need to load a module for CDO, NCO, or Ncview when loading netcdf/4.3.2 or netcdf/4.5.0.
You will need to recompile any applications you maintain which use NetCDF or a related package when moving to CentOS7. You should plan to rebuild all applications you maintain once your system is migrated to CentOS7.
Please note the following NetCDF changes for CentOS7:
- NetCDF 4.3.2 and 4.5.0 are installed. Versions 3.6.3 and 4.1.1 are no longer supported.
- The default version is now NetCDF 4.5.0. This version corrects a known issue with 4.3.2.
- All installations have version 4 features enabled. The netcdf4/ module files are the same as the netcdf/ module files.
- The 4.3.2 and 4.5.0 installations were built using HDF5 1.8.16 for each compiler suite available under CentOS7.
- CDO, NCO, and Ncview are embedded in the 4.3.2 and 4.5.0 installations.
- HDF4 is embedded as part of enabling HDF4 support in the NetCDF installations.
The NetCDF module files set a number of environment variables related to the packages used for the deployment such as $NETCDF_HOME and $HDF5_HOME. You can examine the NetCDF module file(s) by loading the module for your compiler suite and then using:
module show netcdf
We realize these changes may be an inconvenience to some, but are necessary to better support NetCDF going forward in CentOS7. If you see a problem migrating to NetCDF 4.5.0, please contact us at email@example.com.
