Installing NXyn

1. Go to target directory of your choice
   cd ~
2. Download NXyn (via HTTP)
   wget http://www.complang.tuwien.ac.at/skral/NXyn/download/NXyn-1.0.tar.gz
3. Unpack the archive
   tar xzf NXyn-1.0.tar.gz
4. Change directory
   cd NXyn-1.0/
5. Run the installation script
   ./install.sh

Using NXyn

To use NXyn, use nx_gcc instead of gcc and nx_icc instead of icc.

Compiling FFTW with NXyn

1. Go to target directory of your choice
   cd ~
2. Download FFTW (via HTTP)
   wget http://www.fftw.org/fftw-3.2.2.tar.gz
3. Unpack the archive
   tar xzf fftw-3.2.2.tar.gz
4. Change directory
   cd fftw-3.2.2/
5. Run configure script. Depending on the numerical precision and on the C compilers available use one of the following:
   • Intel C Compiler
     • Double precision floating point (SSE2)
       ./configure --disable-shared --disable-threads --enable-static --enable-sse2 --disable-float CC=nx_icc CFLAGS="-O3"
     • Single precision floating point (SSE)
       ./configure --disable-shared --disable-threads --enable-static --enable-sse --enable-float CC=nx_icc CFLAGS="-O3"
   • GNU C Compiler
     • Double precision floating point (SSE2)
       ./configure --disable-shared --disable-threads --enable-static --enable-sse2 --disable-float CC=nx_gcc CFLAGS="-O3"
     • Single precision floating point (SSE)
       ./configure --disable-shared --disable-threads --enable-static --enable-sse --enable-float CC=nx_gcc CFLAGS="-O3"
6. Compile FFTW with NXyn (using 4 parallel processes)
   make -j 4
7. Run FFTW library self-check
   cd tests/ && make bigcheck && cd ../
8. (optional) Install FFTW
   sudo make install
