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-604"></a><a name="index-compiler-605"></a><a name="index-portability-606"></a> + + <p>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-607"></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> +
