07/09/10	SR	r556	3.7a	C	Documentation for surface_heatflux in case of prandtl_layer = .F. improved. bugfix for wrong netcdf/3.6.3 module on lcsgi (mbuild, mrun)
				B	Bugfix in if statement (disturb_heatflux) Bugfix: in 2201 statement: closing " was missing (interpret_config) Bugfix: default setting of nzb_local for flat topography (init_grid) Bugfix: wrong dimension used for ts_value_l (user_statistics)
01/09/10	CH	r553	3.7a	C	d3dpar-parameters for masked output data_output_mask_*, data_output_mask_user_*, mask_*_x, mask_*_y, mask_*_z, mask_*_x_loop, mask_*_y_loop and mask_*_z_loop have been replaced by corresponding (array-) parameters data_output_masks, data_output_masks_user, mask_x, mask_y, mask_z, mask_x_loop, mask_y_loop, and mask_z_loop. inipar-parameter masks has been removed. The changes concern the masked data output, which is still not documented.

21/04/10	RH	r532	3.7a	C	Large scale vertical motion (subsidence/ascent) can be added as additional source to the prognostic equation for humidity/passive scalar. Character length for dopr_unit enlarged. Adjustment of the NCL scripts to allow for output of png files.
				B	Bugfix: unit of hyp changed to dbar (check_parameters)

30/03/10	RH	r526	3.7a	C	Adjustment of the NCL scripts and palmplot to allow for special characters in netCDF variable names.
30/03/10	SR	r525	3.7a	B	Bugfix: "/" in netcdf profile variable names replaced by ":"
19/03/10	SR	r520	3.7a	N	netCDF4 support for particle data. Total number of particles is allowed to increase during the run, when netcdf_data_format > 2 is used.
				C	Special characters like * and " are now allowed for netCDF variable names. Replacement of these characters has been removed (routine clean_netcdf_varname removed)
18/03/10	SR	r516	3.7a	N	Simple installation method has been documented (see doc/install). Respective scripts and configuration files have been updated.
				B	opt=1 is forced for PGI-compiler in routine buoyancy by compiler-directive. Otherwise, program aborts with SIGFPE.
16/03/10	RH	r513	3.7a	N	NCL scripts can be run with the shell script palmplot.
12/03/10	SR	r509	3.7a	B	bugfix for r504: remode_md was given a wrong value
08/03/10	SR	r506	3.7a	C	hack for better usage of mrun on Kyoto computing center machine (lckyoto)
03/03/10	SR	r504	3.7a	C	combine_plot_fields is now directly called within mrun and must not be given by an output command in the configuration file any more. Please remove the respective output command (OC:combine_plot_fields.x) from your configuration file! Utility programs (combine_plot_fields, interpret_config) are created by mbuild separately for each block in the configuration file. Depending on option -K, mrun is using the utility programs for the respective block. Utility programs are also compiled in parallel, depending on variable %mopts in the configuration file.. Default configuration files updated.
02/03/10	SR	r496	3.7a	C	Particle data for restart runs are only written if environment variable write_binary = .T., i.e. particle data are now handled in the same way as the other restart data. (palm)
01/03/10	SR	r494	3.7a	N	Output in netCDF4-format. netCDF4 allows for parallel I/O. Also, variables are not limited in size any more (i.e. arrays can be larger than 2GB). The new d3par-parameter netcdf_data_format can be used to select among the different netCDF file formats (1: classic format, 2: 64-bit-offset format (this is now the default), 3: netCDF4/HDF5 format, 4: netCDF4 format with NF90_CLASSIC_MODEL bit set). Setting netcdf_data_format > 2 only affects 2d- and 3d-output, i.e. there is no parallel output for profiles, time series, spectra, and particles. Parallel output of particle data may be realized in the future. In case of parallel output, all PEs write into one file, which means that postprocessing the data with combine_plot_fields (merging data from single files - one per PE - into one file) is not neccessary. In this case, flag files are automatically set, telling combine_plot_fields that nothing is to be done. Using netCDF4 format requires a netCDF4/HDF5 library. Respective settings for -I, -L, and -l compiler/loader options for the SGI-ICE at HLRN can be found in the new example configuration file .mrun.config.imuk_ice2_netcdf4 Attention: So far, netCDF parallel I/O has only been tested a little. Further performance optimizations may be required, especially in case of large data sets (e.g. data chunking, or lustre file system settings with lfs setstripe). Please report bugs and performance problems immediately! combine_plot_fields outputs cpu-time needed for file merging. Modules to be loaded for compilation (mbuild) or job execution (mrun) can/should now be given in the configuration file (.mrun.config) 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 and remove the %mpilib variable in your configuration file. Compilation time can be reduced be using parallel make. The number of allowed simultaneous compiler calls (threads) is set in the configuration file using variable %mopt, e.g. %mopts -j:4 lcsgih parallel allows a maximum of 4 routines to be compiled simultaneously (provided that the makefile does not show any dependencies between these routines).
				C	d3par-parameters netcdf_64bit and netcdf_64bit_3d have been removed. Use the new d3par-variable netcdf_data_format = 2 for choosing the netCDF 64bit-offset format (this is the default from now on). The offset-format can not be set independently for the 3d-output-data any more. d3par-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. This change concerns the masked data output, which is still not documented.
				B	Bugfix in Makefile​: forgot to compile for interpret_config. Bugfix: timeseries data have to be collected by PE0 (user_statistics).
05/02/10	SR	r484	3.7a	B	ngp_3d, ngp_3d_inner changed to 64 bit. Otherwise, on large grids > 2*109 grid points some global statistics (e.g. total kinetic energy) have wrong values.
