The FFTW library is self-optimizing—it automatically tunes itself for each hardware platform in order to achieve maximum performance. So according to GSL developers' own admission, FFTW is expected to outperform GSL.
WebJun 11, 2024 · I'm testing the FFTW 3.3.8 C library for 1D Discrete Fourier Transform (DFT) calculations. The results I get are often incorrect when I use the float (single-precision) version of the libraries, configured with the --enable-generic-simd128 or --enable-generic-simd256 options (and --enable-float for float support). I have tested this in MinGW-w64 … WebJun 24, 2012 · The equation is: (1) \sum (j=1 to N) (w (i - j) * s_NMDA [j]) where s_NMDA is a vector of length N and w is defined by: (2) w (j) = tanh [1/ (2 * sigma * p)] * exp (-abs (j) / (sigma * p)] where sigma and p are constants. (is there a better way to render equations on stackoverflow?) The calculation has to be done for N neurons.

So I did a simple 1D transformation first, where I know what to expect exactly: Using the same convention as FFTW (normalisation factor=1, oscillatory factor=-2*pi for the forward fourier transform), when I transform 1/2 (δ (1 + x) - δ (1 - x))
WebJul 21, 2024 · regarding fftw, AFAIK, there are no specific performance tips from MKL which would help to accelerate the performance for small cases. Actually the overhead of using fftw from mkl is pretty negligible. regarding your bench: I see you measure the allocation/deallocation parts, creating the fftw plans, memcopy operations as well. But, …
