12 | file</h3> |
---|
13 | <p style="line-height: 100%;">In this chapter a sample |
---|
14 | configuration |
---|
15 | file is described. It contains only instructions which are really |
---|
16 | necessary for the execution of a simple model run (configuration |
---|
17 | files can be much more complex). The example presented here is stored |
---|
18 | in an appropriate <a href="http://www.muk.uni-hannover.de/%7Eraasch/PALM_group/INSTALL/.mrun.config">example |
---|
19 | file</a> (containing more than the configuration data presented |
---|
20 | here) |
---|
21 | and can be used, together with the <a href="http://www.muk.uni-hannover.de/%7Eraasch/PALM_group/INSTALL/example_p3d">parameter |
---|
22 | file</a> presented in <a href="chapter_4.4.html">chapter |
---|
23 | 4.4</a>, for the execution of a simple model run. In chapter 4.4 |
---|
24 | the |
---|
25 | complete <b>mrun</b> options which are necessary for the |
---|
26 | appropriate |
---|
27 | parameter file are described. Furthermore not all details of the |
---|
28 | configuration file are described here. Therefore you should take a |
---|
29 | look at the <a href="http://www.muk.uni-hannover.de/%7Eraasch/Software/mrun_beschreibung.html">mrun</a> |
---|
30 | documentation (sorry: this is only available in German, so far. If you |
---|
31 | think that you |
---|
32 | would profit from an English version, please give a message to the PALM |
---|
33 | group). </p> |
---|
34 | <p style="line-height: 100%;">The following configuration |
---|
35 | data |
---|
36 | exclusively applies to model runs on the IBM Regatta hanni of the |
---|
37 | HLRN when using several processing elements (i.e. for the parallel |
---|
38 | version of the model). The proper installation of the model is |
---|
39 | presumed (see <a href="chapter_5.0.html">chapter |
---|
40 | 5.0</a>). Furthermore it is supposed that the user is located in |
---|
41 | the |
---|
42 | directory <tt><font style="font-size: 10pt;" size="2">$HOME/palm/current_version/SOURCE</font></tt> |
---|
43 | on its local computer. There are the FORTRAN source codes of the |
---|
44 | model (<tt><font style="font-size: 10pt;" size="2">*.f90</font></tt>) |

68 | </b>needs these information, <font color="#000000">because |
---|
69 | for each |
---|
70 | model run the executable is created by compiling the source files.</font> |
---|
71 | Normally, only the main program (palm.f90) will be compiled while all |
---|
72 | other object files are just linked. These object files have already |
---|
73 | been created from the source code files during the installation of the |
---|
74 | model |
---|
75 | (see </font><a href="chapter_5.0.html"><font face="Thorndale, serif">chapter |
---|
76 | 5.0</font></a><font face="Thorndale, serif">). |
---|
77 | <b>mrun</b> uses |
---|
78 | certain standard options for the compilation process. Beyond that you |
---|
79 | can |
---|
80 | declare additional options with the environment variable </font><tt><i><font face="Thorndale, serif">fopts</font></i></tt><font face="Thorndale, serif">. |
---|
81 | Within the value assignment of an environment variable in the |
---|
82 | configuration file no blanks must be |
---|
83 | used. If blanks are necessary they must <font face="Thorndale, serif">be |
---|
84 | replaced </font>by colons (“:”). <b>mrun</b> |
---|
85 | will |
---|
86 | interpret these colons as blanks (2 colons written one behind the |
---|
87 | other will be interpreted as a colon). Thus in the example above </font><tt><font face="Thorndale, serif">fopts |
---|
88 | has the value </font></tt>“<font style="font-size: 10pt; font-family: monospace;" size="2"><i>-O3 |

131 | assignment for the |

133 | “<tt><font style="font-size: 11pt;" size="2">EC:</font></tt>” |
---|
134 | in the first column (comment lines begin with “<tt>#</tt>”). |
---|
135 | Directly |
---|
136 | after the colon Unix commands follow (korn shell syntax) which are |
---|
137 | processed by <b>mrun</b> if errors arise during |
---|
138 | the model run. The command described in the example (<tt><font style="font-size: 10pt;" size="2">cat |
---|
139 | RUN_CONTROL</font></tt>) is executed thereby only on the |
---|
140 | condition that errors during the execution of the model (<tt><font style="font-size: 10pt;" size="2">execution</font></tt>) |
---|
141 | arise. An <b>mrun </b>internal environment variable which |
---|
142 | indicates |
---|
143 | the |
---|
144 | respective abort place in case of errors is <tt><a href="http://www.muk.uni-hannover.de/institut/software/mrun_beschreibung.html#locat">locat</a></tt>. |
---|
145 | In order to determine the actual value of this variable at the |
---|
146 | execution of <b>mrun</b> the “<tt>$</tt>” |
---|
147 | - prefix |
---|
148 | must be protected by a “\” since the configuration |
---|
149 | file has been |
---|
150 | already interpreted once when reading in through <b>mrun</b> |
---|
151 | and the |
---|
152 | value from |
---|
153 | <tt>locat</tt> would then supply the empty character |
---|
154 | string. If |
---|
155 | errors arise during the model run this command |
---|
156 | copies the data written by the model up to then to the local file |
---|
157 | <a href="chapter_3.4.html#RUN_CONTROL">RUN_CONTROL</a> |
---|
158 | on the standard output where they can be checked after |
---|
159 | job end.<font color="#000000"> RUN_CONTROL is an output |
---|
160 | file of the |
---|
161 | model which has to be copied according to the default configuration |
---|
162 | file |
---|
163 | (see below) after the end of the model run to a permanent file of the |
---|
164 | user but this action would not be performed in case of errors |
---|
165 | in the model run, so that the file content would be lost.</font> |
---|
166 | With |
---|
167 | the help of the error command one can secure it nevertheless. </p> |

168 | <p style="line-height: 100%;">Before and/or after |

169 | the error commands in the example file you can find the so-called input |

---|
178 | how to connect |

179 | the local files in the temporary working |
---|
180 | directory of the model with the respective permanent files of the user. |
---|
181 | <b>mrun</b> copies the input and output files in accordance |
---|
182 | with the |
---|
183 | data in these connection statements. The file connection statements are |
---|
184 | explained in detail in the <b>mrun</b> |
---|
185 | description (<a href="http://www.muk.uni-hannover.de/institut/software/mrun_beschreibung.html#chapter6.3">chapter |
---|
186 | 6.3</a>, in German) and are described here only as far as being |
---|
187 | necessary. A |
---|
188 | file connection statement usually consists of entries in 5 columns |
---|
189 | whereby all columns are separated from each other by one or more blanks |
---|
190 | (the blanks define the individual columns). In the |
---|
191 | first column the local file name (e.g. <tt><font size="2">PARIN</font></tt>) |
---|
192 | is given as it is addressed by the model. It must begin directly at |
---|
193 | the start of the line. In the second column the so-called file |
---|
194 | attributes |
---|
195 | are given. These determine whether the file is an input file (<tt><font style="font-size: 10pt;" size="2">in</font></tt>) |
---|
196 | or an output file (<tt><font size="2">out</font></tt>), |
---|
197 | whether output |
---|
198 | files are to be transferred to the local computer of the user (<tt><font style="font-size: 10pt;" size="2">tr</font></tt>) |
---|
199 | or whether they are to be archived (<font size="2"><font face="Cumberland, monospace">fl</font></font>). |
---|
200 | If a file has several attributes then they are separated by a <font color="#000000">colon |
---|
201 | in each case .</font> </p> |
---|
202 | <p style="line-height: 100%;">With the entries in the |
---|
203 | third column one |
---|
204 | specifies the conditions under which a file connection statement |
---|
205 | becomes active i.e. under |
---|
206 | which circumstances it is executed by <b>mrun</b>. Then <b>mrun</b> |
---|
207 | copies the appropriate in or output files only if at least one of the |
---|
208 | character strings registered in column 3 (again two or more character |
---|
209 | strings have to be separated from each other by a colon) is |
---|
210 | indicated within the mrun <b>call</b> by the option <a href="http://www.muk.uni-hannover.de/institut/software/mrun_beschreibung.html#Opt-r">-r</a>. |
---|
211 | Thus a call of the form </p> |
---|
212 | <ul> <pre style="margin-bottom: 0.5cm; line-height: 100%;"><font style="font-size: 10pt;" size="2">mrun - h ibmh -d abcde -r d3</font></pre></ul> |
---|
213 | <p style="line-height: 100%;">would lead to the fact that |
---|
214 | the input |
---|
215 | file with the local name PARIN is made available and the output files |
---|
216 | RUN_CONTROL and HEADER are copied to permanent files. The output |
---|
217 | files PLOT1D_PAR and PLOT1D_DATA are not copied so that their |
---|
218 | contents are not available to the user after the end of the job. If |
---|
219 | these files are to be copied of <b>mrun</b> then the call |
---|
220 | must be</p> |
---|
221 | <ul> <pre style="margin-bottom: 0.5cm; line-height: 100%;"><font style="font-size: 10pt;" size="2">mrun -h ibmh -d abcde -r "d3 pr"</font></pre></ul> |
---|
222 | <p style="line-height: 100%;">Instead of the option -r you |
---|
223 | can |
---|
224 | separately address the file connection statements for input and/or |
---|
225 | output files with the options -i and -o. If one likes to make sure with |
---|
226 | these two options that in the example configuration |
---|
227 | file all file connection statements are actually executed then |
---|
228 | the call must be: </p> |
---|
229 | <ul> <pre style="margin-bottom: 0.5cm; line-height: 100%;"><font style="font-size: 10pt;" size="2">mrun -h ibmh -d abcde -i d3 -o "d3 pr"</font></pre></ul> |

230 | <p style="line-height: 100%;"><font color="#000000">The |
---|
231 | names of the |
---|
232 | local files assigned permanent files are build from the entries in |
---|
233 | the 4th and 5th column of the file connection statements and the |

240 | + “value of the 5th column”.</p> |

241 | </ul><p style="line-height: 100%;">The 4th column |

244 | is replaced by the value indicated for the option <tt><font size="2">-d</font></tt>. |
---|
245 | The 5th column contains the so-called file name extension. The name |

249 | <ul> <pre style="margin-bottom: 0.5cm; line-height: 100%;"><font style="font-size: 10pt;" size="2">~/palm/current_version/JOBS/abcde/INPUT/abcde_p3d.</font></pre></ul> |
---|
250 | <p style="line-height: 100%;">In the same way the names of |
---|
251 | the |
---|
252 | permanent files of the remaining <font color="#000000">file |
---|
253 | connection statements </font>can be formed. </p> |
---|
254 | <p style="line-height: 100%;">With this example |
---|
255 | configuration file |
---|
256 | exactly one input file is copied into the temporary working directory |
---|
257 | of the model. This file has the local name <a href="chapter_3.4.html#PARIN">PARIN</a> |
---|
258 | and contains the steering parameters for the model and has to be |
---|
259 | provided by the user for each model run. </p> |
---|
260 | <p style="line-height: 100%;">The example configuration |
---|
261 | file also |
---|
262 | instructs <b>mrun</b> to copy four output files of the |
---|
263 | model to |
---|
264 | appropriate permanent files of the user at the end of the run. |
---|
265 | There are timestep information (local file name <tt><a href="chapter_3.4.html#RUN_CONTROL">RUN_CONTROL</a></tt>), |
---|
266 | the so-called header file, in which the values of the most selected |
---|
267 | parameters for this run (<tt><a href="chapter_3.4.html#HEADER">HEADER</a></tt>) |
---|
268 | are located, as well as a file with data of horizontally averaged |
---|
269 | vertical profiles |
---|
270 | (<tt><a href="chapter_3.4.html#PLOT1D_DATA">PLOT1D_DATA</a></tt>) |
---|
271 | and an associated parameter file (<tt><a href="chapter_3.4.html#PLOT1D_PAR">PLOT1D_PAR</a></tt>), |
---|
272 | which can be used as input files for the plot program <a href="http://www.muk.uni-hannover.de/institut/software/profil_beschreibung.html">profil</a>. |
---|
273 | A model run does not presuppose neither the file connection statements |
---|
274 | for |
---|
275 | output files nor their activation. But without declaring AND activating |
---|
276 | them usually the data produced by the model |
---|
277 | are lost after the end of the model run! </p> |
---|
278 | <p style="line-height: 100%;">As already mentioned the |
---|
279 | configuration |
---|
280 | file offers a variety of further possibilities to steer the |
---|
281 | execution of the model run. Some of them are described in the next |
---|
282 | chapter. Same applies to possible other options of the <b>mrun</b> |
---|
283 | call. For these please refer to the <a href="http://www.muk.uni-hannover.de/%7Eraasch/Software/mrun_beschreibung.html">mrun</a> |
---|
284 | documentation (in German). An <b>mrun </b>call for the |
---|
285 | execution of a |
---|
286 | model run |
---|
287 | on several processors on the IBM Regatta "hanni" of the HLRN must be |
---|
288 | supplemented by the following options in each case: </p> |
---|
289 | <ul> <pre style="margin-bottom: 0.5cm; line-height: 100%;"><font style="font-size: 10pt;" size="2">mrun - K parallel -X … -t … -m …</font></pre></ul> |
---|
290 | <p style="line-height: 100%;">Only the indication of <tt><font style="font-size: 11pt;" size="2">-K |
---|
291 | parallel</font></tt> causes the parallel execution of the |
---|
292 | run on |
---|
293 | several processors (otherwise a scalar execution on one processor is |
---|
294 | accomplished). In addition to this the number of the |
---|
295 | processing elements which shall be used has to be pre-scribed with the |
---|
296 | option <tt><font style="font-size: 10pt;" size="2">-X</font> |
---|
297 | </tt><font size="2">(</font><font style="font-size: 10pt;" size="2">e.g. |
---|
298 | </font><tt><font style="font-size: 10pt;" size="2">-X |
---|
299 | 4</font></tt><font size="2">).</font> |
---|
300 | In each case the permitted CPU time in seconds and the required memory |
---|
301 | size in MB must be indicated by the options <tt><font style="font-size: 11pt;" size="2">-t</font></tt> |
---|
302 | and <tt><font style="font-size: 11pt;" size="2">-m</font></tt>, |
---|
303 | respectively<font face="Thorndale, serif">.</font> |
---|
304 | Alternatively, these can be set by the appropriate environment |
---|
305 | variables in the configuration file: </p> |
---|
306 | <blockquote style="line-height: 100%;"><tt><font style="font-size: 10pt;" size="2"><font face="Cumberland, monospace">% |
