Danielson lancsoz lemma [g. c. danielson and c. lanczos] and is the basis of fft. . so called fast fourier transform (fft) algorithm reduces the complexity to o(nlogn). danielson lancsoz lemma: x(k) = n 2 x 1 n=0 x(2n)e i 2ˇ (2n)k n n 2 x 1 n=0 x(2n 1)e i 2ˇ (2n 1)k n = n 2 x 1 n=0 x(2n)e i ˇnk n 2 n 2 x 1 n=0 x(2n 1)e i n 2 = dft n 2. Our new 3 d fft kernel, written in nvidia cuda, achieves nearly 80 gflops on a top end gpu, being more than three times faster than any existing fft implementations on gpus including cufft. Comparably, fftw works faster with a single core implementation i presume because the size of the data is small enough to fit on the cpu’s l2 cache. so, i’ve realised that what i need is a batched 3d fft routine, so i can do my many 64^3 ffts. i’ve also realised that i’m going to have to man up and write it myself!.
