cuFFTAdvisor

Tool for generating optimal setting of the cuFFT library.

This tool is able to:

• benchmark some transformation.
• run fast heuristics which will recommend faster settings, using either padding or cropping.
• autotune the heuristics proposals and thus obtainign the best setting possible

Build

Simply run make in the root directory. Make sure that you have NVCC and Cuda libraries in the PATH

Example

./build/cuFFTAdvisor -help

./build/cuFFTAdvisor -benchmark -device 0 -x 85 -y 1

./build/cuFFTAdvisor -recommend 30 -x 2273 -y 2273 -n 6 --outOfPlaceOnly --realOnly --floatOnly --batchOnly --forwardOnly --maxSignalInc 10

./build/cuFFTAdvisor -find 20 -x 445105 -n 5 --inPlaceOnly --complexOnly --doubleOnly --forwardOnly

Known limitations

Internal heuristics is based on Cuda v.8, so it might not be very accurate for other versions.
