	217	<td style="vertical-align: top;">Output in NetCDF4-format.<br>
	218	<br>
	219	NetCDF4 allows for parallel I/O. Also, variables are not limited in
	220	size any more (i.e. arrays can be larger than 2GB). The new
	221	d3par-parameter <span style="font-family: Courier New,Courier,monospace;">netcdf_data_format</span>.can be used to select among the different NetCDF file formats (<span style="font-style: italic;">1</span>: classic format, <span style="font-style: italic;">2</span>: 64-bit-offset format (this is now the default), <span style="font-style: italic;">3</span>: NetCDF4/HDF5 format, <span style="font-style: italic;">4</span>: NetCDF4 format with NF90_CLASSIC_MODEL bit set). Setting <span style="font-family: Courier New,Courier,monospace;">netcdf_data_format</span> > <span style="font-style: italic;">2</span>
	222	only affects 2d- and 3d-output, i.e. there is no parallel output for
	223	profiles, time series, spectra, and particles. Parallel output of
	224	particle data may realized in the future.<br>
	225	<br>
	226	In case of parallel output, all PEs write into one file, which means that postprocessing the data with <span style="font-family: Courier New,Courier,monospace;">combine_plot_fields</span>
	227	(merging data from single files - one per PE - into one file) is not
	228	neccessary. In this case, flag files are automatically set, telling <span style="font-family: Courier New,Courier,monospace;">combine_plot_fields</span> that nothing is to be done.<br>
	229	<br>
	230	Using NetCDF4 format requires a NetCDF4/HDF library. Respective
	231	settings for -I, -L, and -l compiler/loader options for the SGI-ICE at
	232	HLRN can be found in the new example configuration file <span style="font-family: Courier New,Courier,monospace;">..../trunk/SCRIPTS/.mrun.config.imuk_ice2_netcdf4</span><br>
	233	<br>
	234	<span style="font-weight: bold;">Attention:</span><br>
	235	So far, NetCDF parallel I/O has only been tested a little. Further
	236	performance optimizations may be required, especially in case of large
	237	data sets (e.g. data chunking, or lustre file system settings with <span style="font-family: Courier New,Courier,monospace;">lfs setstripe</span>). <span style="font-weight: bold;">Please report bugs and performance problems immediately!</span><br>
	238	<br>
	239	<span style="font-family: Courier New,Courier,monospace;">combine_plot_fields</span> outputs cpu-time needed for file merging.<br>
	240	<br>
	241	Modules to be loaded for compilation (mbuild) or job execution (mrun) can/should now be given in the configuration file (<span style="font-family: Courier New,Courier,monospace;">.mrun.config</span>) using variable <span style="font-family: Courier New,Courier,monospace;">modules</span>. Example:<br>
	242	<br>
	243	<span style="font-family: Courier New,Courier,monospace;">   %modules     ifort/11.0.069:netcdf       lcsgih parallel</span><br>
	244	<br>
	245	This method replaces the (undocumented) <span style="font-family: Courier New,Courier,monospace;">mpilib</span>-variable.<br>
	246	<br>
	247	<span style="font-weight: bold;">WARNING:</span><br>
[497]	248	<span style="font-weight: bold;">All fixed settings of modules in the scripts mbuild, mrun, and subjob have been removed! Please set the <span style="font-family: Courier New,Courier,monospace;">modules</span> variable appropriately and remove the mpilib variable in your configuration file.<br>
	249	<br>
	250	</span>Compilation time can be reduced be using parallel make. The
	251	number of allowed simultaneous compiler calls (threads) is set in the
	252	configuration file using variable <span style="font-family: Courier New,Courier,monospace;">mopt</span>, e.g.<br>
	253	<br>
	254	<span style="font-family: Courier New,Courier,monospace;">   %mopts  -j:4   lcsgih parallel</span><br>
	255	<br>
	256	allows a maximum of 4 routines to be compiled simultaneously (provided
	257	that the makefile does not show any dependencies between these
	258	routines).<span style="font-weight: bold;"><br>

	1153	<h2><a name="Kapitel2.0"></a>2.0  How
[493]	1154	to change the source
	1155	code and how to document modifications<br>
	1156	</h2>Currently
[392]	1157	(Sep 23rd, 2009), only selected users are allowed to commit changes to
[493]	1158	the repository. Rules given below are preliminary, until we have switched to the "trac"-System.<br>
	1159	<br>
	1160	<ol>
	1161	<li>Change source code in your current working copy. Document changes in the respective file headers unter "<span style="font-family: Courier New,Courier,monospace;">Current revisions:</span>".
	1162	Additionally, document all changes in a local file (e.g.
	1163	~/palm/current_version/CURRENT_MODIFICATIONS), including the files that
	1164	have been changed. Classify changes in three cases, new (N), changed
	1165	(C), and bugfix (B). <span style="font-weight: bold;">Try to be as short and as precise as possible in describing the changes!</span><br>
	1166	<br>
	1167	</li>
	1168	<li>Test the changed version, unless it works sufficiently.<br>
	1169	<br>
	1170	</li>
	1171
	1172	<li>Commit the changes to the repository<br>
	1173	<br>
	1174	<span style="font-family: Courier New,Courier,monospace;">   svn commit -m "message string" trunk<br>
	1175	</span><br>
	1176	where "<span style="font-family: Courier New,Courier,monospace;">message string</span>" is a short, <span style="font-weight: bold;">meaningful</span> summary of the changes.<br>
	1177	<br>
	1178	Alternatively, in case that you have made quite a lot of changes, you
	1179	can also give the contents of your file CURRENT_MODIFICATIONS as the
	1180	log message:<br>
	1181	<br>
	1182	<span style="font-family: Courier New,Courier,monospace;">   svn commit -F CURRENT_MODIFICATIONS trunk</span><br>
	1183	<br>
	1184	</li>
	1185
	1186	<li>Enter the changes into the technical documentation (under <span style="font-family: Courier New,Courier,monospace;">.../trunk/DOC/tec/technical_documentation.html</span>).<br>
	1187	<br>
	1188	</li>
	1189	<li>Move the change comments in the file headers from "Current
	1190	revisions:" to "Former revisions:". Set the current svn id in front of
	1191	that.<br>
