<br/>
CppAD has a set of speed tests for just calculating functions
(in double precision instead of an AD type).
This section links to the source code the function value speed tests.

<br/>
<br/>
<b><big><a name="Running Tests" id="Running Tests">Running Tests</a></big></b>
<br/>
To build these speed tests, and run their correctness tests,
execute the following commands starting in the
<a href="installunix.xml#Work Directory" target="_top"><span style='white-space: nowrap'>work&#xA0;directory</span></a>
:

<code><font color="blue"><span style='white-space: nowrap'><br/>
&#xA0;&#xA0;&#xA0;&#xA0;&#xA0;cd&#xA0;speed/double<br/>
&#xA0;&#xA0;&#xA0;&#xA0;&#xA0;make&#xA0;test<br/>
</span></font></code>
You can then run the corresponding speed tests 
with the following command

<code><font color="blue"><span style='white-space: nowrap'><br/>
&#xA0;&#xA0;&#xA0;&#xA0;&#xA0;./double&#xA0;speed&#xA0;</span></font><i><font color="black"><span style='white-space: nowrap'>seed</span></font></i><font color="blue"><span style='white-space: nowrap'><br/>
</span></font></code>
where 
<code><i><font color="black"><span style='white-space: nowrap'>seed</span></font></i></code>
 is a positive integer.
See <a href="speed_main.xml" target="_top"><span style='white-space: nowrap'>speed_main</span></a>
 for more options.

<br/>
<br/>
<b><big><a name="C++ Compiler Flags" id="C++ Compiler Flags">C++ Compiler Flags</a></big></b>
<br/>
The C++ compiler flags used to build the <code><font color="blue">double</font></code> program are
<code><font color="blue">
<pre style='display:inline'> 
     AM_CXXFLAGS   = -O2 -DNDEBUG -DCPPAD_DOUBLE_SPEED $(CXX_FLAGS)
</pre>

</font></code>
where <code><font color="blue">CXX_FLAGS</font></code> is specified by the 
<a href="installunix.xml#Configure" target="_top"><span style='white-space: nowrap'>configure</span></a>
 command.
