WebCUFFT Performance vs. FFTW Group at University of Waterloo did some benchmarks to compare CUFFT to FFTW. They found that, in general: • CUFFT is good for larger, power-of-two sized FFT’s • CUFFT is not good for small sized FFT’s • CPUs can ﬁt all the data in their cache • GPUs data transfer from global memory takes too long ... WebFFTW is the most popular FFT library. It has planty of features and it's often used as the reference point, but a number of other libraries has comparable or better performance. Intel MKL library, which is now freely redistributable, is significantly faster than FFTW. I'm curious if it's also true on non-Intel processors, but I don't have one ...

Web4 Benchmarks In Fig. 1 we show the results of one of the benchmarks for the Itanium nodes. First, we see that the best libraries are intel MKL ones followed by FFTW3, while others have a lower performance. In this particular benchmark the dif-ference between MKL and FFTW3 is the biggest one, but in other benchmarks are quite similar. http://www.fftw.org/speed/ half asleep chris catio
