NetCDF

The Network Common Data Form NetCDF (and its parallel manifestation NetCDF parallel) is a standard library and data format developed and supported by UCAR is released under a BSD-like license.

Both serial and parallel versions are available on ARCHER2 as standard modules:

• module load cray-netcdf (serial version)
• module load cray-netcdf-hdf5parallel (MPI parallel version)

Note that one should first load the relevant HDF module file, e.g.,

$ module load cray-hdf5
$ module load cray-netcdf

for the serial version.

Use module spider to locate available versions, and use module help to locate cray-specific release notes on a particular version.

Known issues:

Full system

• There is currently a problem with the module file which means cray-netcdf-hdf5parallel will not operate correctly in PrgEnv-aocc. One can load module epcc-netcdf-hdf5parallel instead as a work-around if PrgEnv-aocc is required.

4-cabinet system

• There are no currently known issues.

Some general comments and information on serial and parallel I/O to ARCHER2 are given in the section on I/O and file systems.
