cuFFT VI Input and Output are Identical in LabVIEW GPU Analysis Toolkit

Issue Details

I'm using the LabVIEW GPU Analysis Toolkit for FFT processing. When I use the cuFFT VI, the results of the FFT are the same as the input data.

Solution

The CUDA Toolkit driver that the GPU Analysis library depends on removed support for 32-bit Windows in version 7.0. As a result, you cannot use LabVIEW 32-bit with newer versions of the CUDA driver. If you'd like to use the LabVIEW GPU Analysis Toolkit for FFT, you have the following options:

  • Use LabVIEW 64-bit on a Windows 64-bit system
  • Revert to an older version of the CUDA driver (older than 7.0)
