This is a fork of FFTW3 to add more SIMD architectures, and to improve existing ones. Our optimization targets are the small 3D FFTs used in GROMACS (but it will never reduce performance). Current additions include Power8 (VSX, single/double), AVX (128 bit enabled together with 256 bits), AVX2 (128 & 256 bits).
