Hello,
Can you please share the input data, the output data, the data you expected and the GPU name so I can check it? Thank you!
Best regards,

Hi Dmitrii,
Ok. The input data is just test sample data generated by gnu radio in IQIQIQ.. format, i've provided it as fftData.iq The data I expect is close to the cufft_output.csv I am providing (I have confirmed that data is good, it was generated by a NVIDIA device and their cuda library with the same input data). The output data generated by performVulkanFFT is attached as vkfft_output.csv.

Re GPU name, it's the vulcan processor in the raspberry pi 4.

Hm, I get the same result in cuFFT as in VkFFT (starting with 7836 and 2061)
You can check it if you add the following code before cout about line 664:
#ifdef USE_cuFFT
uint32_t dims[4] = {8192,1,1,1};
float* output_extFFT = (float*)(malloc(2*sizeof(float) * dims[0] * dims[1] * dims[2]));
launch_precision_cuFFT_single(buffer_input, (void*)output_extFFT, dims);
for (int x=0; x < 30; x++) {
printf("value: %f \n", output_extFFT[x]);
}
#endif // USE_cuFFT
Maybe there is some issue with data reading/processing?
Best regards,
