| 11 | </font></h3><p style="line-height: 100%;">Users |
|---|
| 12 | can add their own (modified) user-interface to a PALM-run by carrying |
|---|
| 13 | out the following steps:</p><ol><li>Copy the appropriate default |
|---|
| 14 | (empty) user-interface files<span style="font-family: Courier New,Courier,monospace;"> |
|---|
| 15 | user_***.f90</span> to a directory of your choice, e.g.:<br><br><span style="font-family: Courier New,Courier,monospace;"> |
|---|
| 16 | cd ~/palm/current_version</span><br style="font-family: Courier New,Courier,monospace;"><span style="font-family: Courier New,Courier,monospace;"> |
|---|
| 17 | mkdir -p USER_CODE/example</span><br style="font-family: Courier New,Courier,monospace;"><span style="font-family: Courier New,Courier,monospace;"> |
|---|
| 18 | cp trunk/SOURCE/user_***.f90 |
|---|
| 19 | USER_CODE/example<br><br><span style="font-family: Times New Roman,Times,serif; font-weight: bold;">Attention: do not change the filenames!</span><br></span><br></li><li>Set |
|---|
| 20 | an additional path in the configuration file<span style="font-family: Courier New,Courier,monospace;"> |
|---|
| 21 | .mrun.config </span>to allow <span style="font-weight: bold;">mrun |
|---|
| 22 | </span>to find and include these files:<br><br><span style="font-family: Courier New,Courier,monospace;"> |
|---|
| 23 | %add_source_path |
|---|
| 24 | $base_directory/USER_CODE/$fname</span><br><br>The |
|---|
| 25 | default configuration file (<span style="font-family: Courier New,Courier,monospace;">trunk/SCRIPTS/.mrun.config.default</span>) |
|---|
| 26 | already includes this setting.<br></li><li>Modify the interface |
|---|
| 27 | routines according to your needs.<br></li><li>Start a PALM run |
|---|
| 28 | by executing<br><br><span style="font-family: Courier New,Courier,monospace;"> |
|---|
| 29 | mrun -d example ...</span><br><br>The files<span style="font-family: Courier New,Courier,monospace;"> |
|---|
| 30 | user_***.f90 </span>will be automatically compiled within |
|---|
| 31 | the job and will replace the respective PALM‘s default user-interface routines.<br></li></ol>The |
|---|
| 32 | above method with including<span style="font-family: Courier New,Courier,monospace;"> $fname </span>in |
|---|
| 33 | the additional source path allows to use different user-interfaces for |
|---|
| 34 | different runs at the same time. Just store the respective |
|---|
| 35 | interface-files in subdirectories<span style="font-family: Courier New,Courier,monospace;"> |
|---|
| 36 | USER_CODE/abcd</span>,<span style="font-family: Courier New,Courier,monospace;"> |
|---|
| 37 | USER_CODE/cdef</span>, etc. and start <span style="font-weight: bold;">mrun</span> with option |
|---|
| 38 | “<span style="font-family: Courier New,Courier,monospace;">-d |
|---|
| 39 | abcd</span>“, “<span style="font-family: Courier New,Courier,monospace;">-d cdef</span>“, |
|---|
| 40 | etc.<br><br>If the user wants to add additional routines, he/she can a) put them into the default user-interface file <span style="font-family: Courier New,Courier,monospace;">user_additional_routines.f90</span> |
|---|
| 41 | or b) can create new files in the additional source directory. These |
|---|
| 42 | files must have names different from the default PALM source code |
|---|
| 43 | files. In case of b), the user must also copy the default makefile into |
|---|
| 44 | the additional source directory:<br><br><span style="font-family: Courier New,Courier,monospace;"> cp trunk/SOURCE/Makefile |
|---|
| 45 | USER_CODE/example</span><br><br>The makefile must be modified appropriately followinf the "make"-rules in order to allow the new files to be compiled.<br><br><span style="font-weight: bold;">The |
|---|
| 46 | modified user-interface files cannot be pre-compiled by using mbuild!</span><br><br>While |
|---|
| 47 | programming user-defined code, |
|---|
| 48 | errors are frequently made. Possible ways of error |
|---|
| 49 | tracing are described in the next chapter. <br><p style="line-height: 100%;"> |
