init_masks.f90 @ 493

Last change on this file since 493 was 493, checked in by raasch, 14 years ago

New:
---
Output in NetCDF4-format. New d3par-parameter netcdf_data_format.

(check_open, check_parameters, close_file, data_output_2d, data_output_3d, header, modules, netcdf, parin)

Modules to be loaded for compilation (mbuild) or job execution (mrun)
can be given in the configuration file using variable modules. Example:

%modules ifort/11.0.069:netcdf lcsgih parallel

This method replaces the (undocumented) mpilib-variable.

WARNING: All fixed settings of modules in the scripts mbuild, mrun, and subjob
have been removed! Please set the modules variable appropriately in your
configuration file. (mbuild, mrun, subjob)

Changed:

Parameters netcdf_64bit and netcdf_64bit_3d have been removed. Use
netcdf_data_format = 2 for choosing the classic 64bit-offset format (this is
the default). The offset-format can not be set independently for the
3d-output-data any more.

Parameters netcdf_format_mask, netcdf_format_mask_av, and variables
nc_format_mask, format_parallel_io removed. They are replaced by the new
parameter netcdf_data_format. (check_open, close_file,
data_output_mask, header, init_masks, modules, parin)

Errors:

bugfix in trunk/UTIL/Makefile: forgot to compile for interpret_config

Bugfix: timeseries data have to be collected by PE0 (user_statistics)
