On Unix systems, the FFTW MPI libraries and header +files are automatically configured, compiled, and installed along with +the uniprocessor FFTW libraries simply by including +<code>--enable-mpi</code> in the flags to the <code>configure</code> script +(see <a href="Installation-on-Unix.html#Installation-on-Unix">Installation on Unix</a>). +<a name="index-configure-349"></a> + + <p>Any implementation of the MPI standard, version 1 or later, should +work with FFTW. The <code>configure</code> script will attempt to +automatically detect how to compile and link code using your MPI +implementation. In some cases, especially if you have multiple +different MPI implementations installed or have an unusual MPI +software package, you may need to provide this information explicitly. + + <p>Most commonly, one compiles MPI code by invoking a special compiler +command, typically <code>mpicc</code> for C code. The <code>configure</code> +script knows the most common names for this command, but you can +specify the MPI compilation command explicitly by setting the +<code>MPICC</code> variable, as in ‘<samp><span class="samp">./configure MPICC=mpicc ...</span></samp>’. +<a name="index-mpicc-350"></a> + + <p>If, instead of a special compiler command, you need to link a certain +library, you can specify the link command via the <code>MPILIBS</code> +variable, as in ‘<samp><span class="samp">./configure MPILIBS=-lmpi ...</span></samp>’. Note that if +your MPI library is installed in a non-standard location (one the +compiler does not know about by default), you may also have to specify +the location of the library and header files via <code>LDFLAGS</code> and +<code>CPPFLAGS</code> variables, respectively, as in ‘<samp><span class="samp">./configure +LDFLAGS=-L/path/to/mpi/libs CPPFLAGS=-I/path/to/mpi/include ...</span></samp>’. + +<!-- --> + </body></html> +
