385      <br>
386NetCDF4 allows for parallel I/O. Also, variables are not limited in
387size any more (i.e. arrays can be larger than 2GB). The new
388d3par-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> &gt; <span style="font-style: italic;">2</span>
389only affects 2d- and 3d-output, i.e. there is no parallel output for
390profiles, time series, spectra, and particles. Parallel output of
391particle data may realized in the future.<br>
392      <br>
393In 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>
394(merging data from single files - one per PE - into one file) is not
395neccessary. 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>
396      <br>
397Using NetCDF4 format requires a NetCDF4/HDF library. Respective
398settings for -I, -L, and -l compiler/loader options for the SGI-ICE at
399HLRN 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>
400      <br>
401      <span style="font-weight: bold;">Attention:</span><br>
402So far, NetCDF parallel I/O has only been tested a little. Further
403performance optimizations may be required, especially in case of large
404data 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>
405      <br>
406      <span style="font-family: Courier New,Courier,monospace;">combine_plot_fields</span> outputs cpu-time needed for file merging.<br>
407      <br>
408Modules 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>

1104release contains further additions, changes, and bugfixes for the
1105SGI-ICE system, as well as important changes like the splitting of the

1107pre-compiling mechanism allowing to use different make-depositories
1108simultaneously, and a revision of the reading-mechanism from restart
1109files, which has no more restrictions in case that the previous and

1320<h2><a name="Kapitel2.0"></a>2.0&nbsp; How
1321to change the source
1322code and how to document modifications<br>
1323</h2>Currently
1324(Sep 23rd, 2009), only selected users are allowed to commit changes to
1325the repository. Rules given below are preliminary, until we have switched to the "trac"-System.<br>
1326<br>
1327<ol>
1328  <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>".
1329Additionally, document all changes in a local file (e.g.
1330~/palm/current_version/CURRENT_MODIFICATIONS), including the files that
1331have been changed. Classify changes in three cases, new (N), changed
1332(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>
1333    <br>
1334  </li>
1335  <li>Test the changed version, unless it works sufficiently.<br>
1336    <br>
1337  </li>
1338 
1339  <li>Commit the changes to the repository<br>
1340    <br>
1341    <span style="font-family: Courier New,Courier,monospace;">&nbsp;&nbsp; svn commit -m "message string" trunk<br>
1342    </span><br>
1343where "<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>
1344    <br>
1345Alternatively, in case that you have made quite a lot of changes, you
1346can also give the contents of your file CURRENT_MODIFICATIONS as the
1347log message:<br>
1348    <br>
1349    <span style="font-family: Courier New,Courier,monospace;">&nbsp;&nbsp; svn commit -F CURRENT_MODIFICATIONS trunk</span><br>
1350    <br>
1351  </li>
1352
1353  <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>
1354    <br>
1355  </li>
1356  <li>Move the change comments in the file headers from "Current
1357revisions:" to "Former revisions:". Set the current svn id in front of
1358that.<br>
