Hi, Attached is a patch which enables FFTW3 to be used by libspeexdsp. Using SSE, the FFT code is more than twice as fast, and it's 50% faster even without SSE. To enable the library, you'll need to call configure with '--with-gpl-fftw3'. Based on the benchmarking we did, this also changes the default FFT to smallft for...

Small update. This makes --without-gpl-fftw3 do the expected, and also allow --with-gpl-fftw3=/path/to/fftw3 for alternate installs. It also zeroes the imaginary of the nyquist element; it works without it, but it's recommended to do. -------------- next part -------------- An embedded and charset-unspecified text was scrubbed...

I installed the (binary) biOps package, which can use libtiff and libfftw. Then I used macports to install the libraries (in /opt/local/lib). But I restart R and biOps still does not see the libraries. I've tried adding symbolic links from /opt/local/lib to /usr/local/lib, I've added /opt/local/lib to LIBRARY_PATH, LD_LIBRARY_PATH, and DYLD_LIBRARY_PATH, and it doesn't work. Do you

And here's a patch for Intel Math Kernel Library. This allows commercial users of Speex to use a high-speed FFT library that isn't GPL'd. (You do need to pay for it though). This is 3 times faster than the default FFT in speex, and also faster than FFTW3 since MKL has native support for the complex packing Speex uses. Since Intel hasn't supplied any pkg-config files, and which libraries to use depend on the platform and compiler, this requires a bit of setup to get working. For me, the correct configure line is: bash autogen.sh && C...

All, the MacOSX binary build of the biOps package is broken on cran, so I am trying to compile from source. I am very close; the trick is apparently that this package depends on fftw3, libjpeg and libtiff. My fftw3 is in /usr/local/, but my libjpeg and libtiff are in /opt/local/ since i got them through macports. In general, I'd like to keep as many of my third-party libraries as I can in the macports system, which means that I need to point R CMD INSTALL to /opt/local. Here...

When built with --with-fft=gpl-fftw3, libspeexdsp is not linked with libfftw3, while it uses symbols from it. This means every object linked with libspeexdsp should also be linked with libfftw3, but it is not something reflected in the pkgconfig file. Instead, link libspeexdsp with libfftw3 when --with-fft=gpl-fftw3, and remove expli...

Attached is the very verbose ssh output. Just to be perverse, this time two nodes lost connectivity. The only thing I see is lines saying that the two connections are lost, although being honest I have no idea what everything else means. For reference, 8 ssh cinnections were being made at the same time for a 8x8mpi task. N.B., since the OS I am using does not have rsh, I am currently using the
