We'll walk you through the compilation of "exp4" which simulates zonal |
| 15 |
adcroft |
1.1 |
flow over a Gaussian bump. |
| 16 |
|
|
<p>From the top-level source directory, where you installed the code, cd |
| 17 |
|
|
to verification/exp4: |
| 18 |
|
|
<blockquote> |
| 19 |
|
|
<pre>% cd verification/exp4</pre> |
| 20 |
|
|
</blockquote> |

There are four sub-directories and a README file. |

<ul> |
| 23 |
|
|
<li> |
| 24 |
|
|
<i>CVS/ </i>is where version information is stored by CVS. You should never |
| 25 |
|
|
need to enter/read/change this.</li> |
| 26 |
|
|
|
| 27 |
|
|
<br><b><i>Please don't delete this directory/information.</i></b> |
| 28 |
|
|
<li> |
| 29 |
|
|
<i>code/ </i>contains copies of the source code unique to this experiment |
| 30 |
|
|
that over-ride the originals. This is our way of customizing the code.</li> |
| 31 |
|
|
|
| 32 |
|
|
<li> |
| 33 |
|
|
<i>input/</i> contains the input files and parameters for this experiment.</li> |
| 34 |
|
|
|
| 35 |
|
|
<li> |
| 36 |
|
|
<i>results/</i> contains a single text file, <i>output.txt</i>, which we |
| 37 |
|
|
use for quickly assessing the state of the code.</li> |
| 38 |
|
|
</ul> |
| 39 |
|
|
Now cd into <i>input/</i> and run the configuration tool <i>genmake</i>: |
| 40 |
|
|
<blockquote> |
| 41 |
|
|
<pre>% cd input</pre> |
| 42 |
|
|
|
| 43 |
|
|
<pre>% ../../../tools/genmake -mods=../code</pre> |
| 44 |
|
|
|
| 45 |
|
|
<pre>% make depend</pre> |
| 46 |
|
|
</blockquote> |
| 47 |
|
|
<i>genmake</i> will create a file <i>Makefile </i>and report which packages |
| 48 |
|
|
are being included/excluded. <i>make depend</i> figures out the file dependancies |
| 49 |
|
|
that allows <i>make</i> to work efficiently. You'll also notice the number |
| 50 |
|
|
of files in the current directory has greatly expanded. This are all symbolic |
| 51 |
|
|
links to the original source code. |
| 52 |
|
|
<p>You only need to do the above steps once; here after, you can edit the |
| 53 |
|
|
code and re-compile with <i>make</i>. |
| 54 |
|
|
<p>Compile and link the code: |
| 55 |
|
|
<blockquote> |
| 56 |
|
|
<pre>% make</pre> |
| 57 |
|
|
</blockquote> |
| 58 |
|
|
This will take some time, depending on your system. [Hint: compiling on |
| 59 |
|
|
remotely mounted disks is often really slow] |
| 60 |
|
|
<p>If all goes well, you're ready to <a href="runModel.html">run the model</a>... |
