I am joining a team which is working heavily with CUDA and am currently configuring my computer to run the code. It seems everything is working except for the cufftExecR2C call, which returns all 0 regardless of the input. I know the code I’m running the tests on is correct, as the same tests run correctly on every other persons computer here.
So my question is, what configuration settings could cause the FFT to fail on one computer when the code works for another? I’m passing all of the other tests, so most of CUDA and JCufft appears to be configured correctly.
