+'''Changed:'''\\
+Adjustments for parallel NetCDF output for lccrayh/lccrayb (Cray XC30 systems). \\\\
+Environmental variables are set (.mrun.config.hlrnIII). \\
+To increase the performance of the parallel NetCDF output, the following is done:
+- The time dimensions are limited (check_parameters, data_output_2d, data_output_3d, header, netcdf, modules, read_var_list, write_var_list),
+- Update time axis by PE0 only (data_output_2d, data_output_3d),
+- Cross sections are first stored on a local array and are outputted collective (data_output_2d, netcdf),
+- Values for axis data are only written by PE0 (netcdf) and
+- No fill is set (netcdf).
+'''Attention:''' So far, parallel NetCDF output is only available for 2D- and 3D-data and not for masked data. \\
+If the user choose [wiki:doc/app/d3par#netcdf_data_format netcdf_data_format] five or six, parallel output is used for 2D- and 3D-data and for masked data [wiki:doc/app/d3par#netcdf_data_format netcdf_data_format] is set internally to the value of three or four, respectively (check_parameters, time_integration).
