Cufft throughput
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 ...

WebApr 27, 2016 · cuFFT performs un-normalized FFTs; that is, performing a forward FFT on an input data set followed by an inverse FFT on the resulting set yields data that is equal to the input, scaled by the number of elements. Scaling either transform by the reciprocal of the size of the data set is left for the user to perform as seen fit. WebJan 24, 2009 · To make a FFT testing with double precision in CUDA, ,I made a simple change for 090808 code, And the result is really bad. While N=1024 batch=16384 , I got only 8 Gflop/s in a tesla c1060 system, while the single version is about 200 Gflops/s. Did someone get better result while using double precision ? BTW, I use cos(phi) and …
WebFeb 18, 2024 · Hello all, I am having trouble selecting the appropriate GPU for my application, which is to take FFTs on streaming input data at high throughput. The marketing info for high end GPUs claim >10 TFLOPS of performance and >600 GB/s of memory bandwidth, but what does a real streaming cuFFT look like? I.e. how do these … WebNov 10, 2009 · The FFT is done using CUFFT with toolkit 2.3 for complex single precision, i.e. 8 bytes per element. ... Larger input datasets in cuFFT means more blocks per FFT, which is usually good for GPU throughput. And yes, Excel is unspeakably uncool (as well as ugly as hell and really unsuited to just about any serious scientific endeavour). Matlab …
