However, planner time is drastically reduced if -FFTW can exploit a hardware cycle counter; FFTW comes with cycle-counter -support for all modern general-purpose CPUs, but you may need to add a -couple of lines of code if your compiler is not yet supported -(see <a href="Cycle-Counters.html#Cycle-Counters">Cycle Counters</a>). (On Unix, there will be a warning at the end -of the <code>configure</code> output if no cycle counter is found.) -<a name="index-cycle-counter-358"></a><a name="index-compiler-359"></a><a name="index-portability-360"></a> -Installation of FFTW is simplest if you have a Unix or a GNU system, -such as GNU/Linux, and we describe this case in the first section below, -including the use of special configuration options to e.g. install -different precisions or exploit optimizations for particular -architectures (e.g. SIMD). Compilation on non-Unix systems is a more -manual process, but we outline the procedure in the second section. It -is also likely that pre-compiled binaries will be available for popular -systems. - - <p>Finally, we describe how you can customize FFTW for particular needs by -generating <em>codelets</em> for fast transforms of sizes not supported -efficiently by the standard FFTW distribution. -<a name="index-codelet-361"></a> - -<ul class="menu"> -<li><a accesskey="1" href="Installation-on-Unix.html#Installation-on-Unix">Installation on Unix</a> -<li><a accesskey="2" href="Installation-on-non_002dUnix-systems.html#Installation-on-non_002dUnix-systems">Installation on non-Unix systems</a> -<li><a accesskey="3" href="Cycle-Counters.html#Cycle-Counters">Cycle Counters</a> -<li><a accesskey="4" href="Generating-your-own-code.html#Generating-your-own-code">Generating your own code</a> -</ul> - -<!-- --> -</body></html> -
