Under <span class="emphasis"><em>boost-path</em></span>/libs/math/reporting/performance you will
|
|
find some reasonable comprehensive performance test applications for this library.
|
|
</p>
|
|
<p>
|
|
In order to generate the tables you will have seen in this documentation (or
|
|
others for your specific compiler) you need to invoke <code class="computeroutput"><span class="identifier">bjam</span></code>
|
|
in this directory, using a C++11 capable compiler. Note that results extend/overwrite
|
|
whatever is already present in <span class="emphasis"><em>boost-path</em></span>/libs/math/reporting/performance/doc/performance_tables.qbk,
|
|
you may want to delete this file before you begin so as to make a fresh start
|
|
for your particular system.
|
|
</p>
|
|
<p>
|
|
The programs produce results in Boost's Quickbook format which is not terribly
|
|
human readable. If you configure your user-config.jam to be able to build Docbook
|
|
documentation, then you will also get a full summary of all the data in HTML
|
|
format in <span class="emphasis"><em>boost-path</em></span>/libs/math/reporting/performance/html/index.html.
|
|
Assuming you're on a 'nix-like platform the procedure to do this is to first
|
|
install the <code class="computeroutput"><span class="identifier">xsltproc</span></code>, <code class="computeroutput"><span class="identifier">Docbook</span> <span class="identifier">DTD</span></code>,
|
|
and <code class="computeroutput"><span class="identifier">Bookbook</span> <span class="identifier">XSL</span></code>
|
|
packages. Then:
|
|
</p>
|
|
<div class="itemizedlist"><ul class="itemizedlist" style="list-style-type: disc; ">
|
|
<li class="listitem">
|
|
Copy <span class="emphasis"><em>boost-path</em></span>/tools/build/example/user-config.jam
|
|
to your home directory.
|
|
</li>
|
|
<li class="listitem">
|
|
Add <code class="computeroutput"><span class="keyword">using</span> <span class="identifier">xsltproc</span>
|
|
<span class="special">;</span></code> to the end of the file (note the
|
|
space surrounding each token, including the final ";", this is
|
|
important!) This assumes that <code class="computeroutput"><span class="identifier">xsltproc</span></code>
|
|
is in your path.
|
|
</li>
|
|
<li class="listitem">
|
|
Add <code class="computeroutput"><span class="keyword">using</span> <span class="identifier">boostbook</span>
|
|
<span class="special">:</span> <span class="identifier">path</span><span class="special">-</span><span class="identifier">to</span><span class="special">-</span><span class="identifier">xsl</span><span class="special">-</span><span class="identifier">stylesheets</span> <span class="special">:</span>
|
|
<span class="identifier">path</span><span class="special">-</span><span class="identifier">to</span><span class="special">-</span><span class="identifier">dtd</span>
|
|
<span class="special">;</span></code> to the end of the file. The <code class="computeroutput"><span class="identifier">path</span><span class="special">-</span><span class="identifier">to</span><span class="special">-</span><span class="identifier">dtd</span></code>
|
|
should point to version 4.2.x of the Docbook DTD, while <code class="computeroutput"><span class="identifier">path</span><span class="special">-</span><span class="identifier">to</span><span class="special">-</span><span class="identifier">xsl</span><span class="special">-</span><span class="identifier">stylesheets</span></code> should point to the folder
|
|
containing the latest XSLT stylesheets. Both paths should use all forward
|
|
slashes even on Windows.
|
|
</li>
|
|
</ul></div>
|
|
<p>
|
|
At this point you should be able to run the tests and generate the HTML summary,
|
|
if GSL, RMath or libstdc++ are present in the compilers path they will be automatically
|
|
tested. For DCDFLIB you will need to place the C source in <span class="emphasis"><em>boost-path</em></span>/libs/math/reporting/performance/third_party/dcdflib.
|
|
</p>
|
|
<p>
|
|
If you want to compare multiple compilers, or multiple options for one compiler,
|
|
then you will need to invoke <code class="computeroutput"><span class="identifier">bjam</span></code>
|
|
multiple times, once for each compiler. Note that in order to test multiple
|
|
configurations of the same compiler, each has to be given a unique name in
|
|
the test program, otherwise they all edit the same table cells. Suppose you
|
|
want to test GCC with and without the -ffast-math option, in this case bjam
|
|
would be invoked first as:
|
|
</p>
|
|
<pre class="programlisting"><span class="identifier">bjam</span> <span class="identifier">toolset</span><span class="special">=</span><span class="identifier">gcc</span> <span class="special">-</span><span class="identifier">a</span> <span class="identifier">cxxflags</span><span class="special">=-</span><span class="identifier">std</span><span class="special">=</span><span class="identifier">gnu</span><span class="special">++</span><span class="number">11</span>
|
|
</pre>
|
|
<p>
|
|
Which would run the tests using default optimization options (-O3), we can
|
|
then run again using -ffast-math:
|
|
</p>
|
|
<pre class="programlisting"><span class="identifier">bjam</span> <span class="identifier">toolset</span><span class="special">=</span><span class="identifier">gcc</span> <span class="special">-</span><span class="identifier">a</span> <span class="identifier">cxxflags</span><span class="special">=</span><span class="char">'-std=gnu++11 -ffast-math'</span> <span class="identifier">define</span><span class="special">=</span><span class="identifier">COMPILER_NAME</span><span class="special">=</span><span class="char">'"GCC with -ffast-math"'</span>
|
|
</pre>
|
|
<p>
|
|
In the command line above, the -a flag forces a full rebuild, and the preprocessor
|
|
define COMPILER_NAME needs to be set to a string literal describing the compiler
|
|
configuration, hence the double quotes - one for the command line, one for
|
|
the compiler.
