%description
The clFFT library is an open source OpenCL library implementation of
discrete Fast Fourier Transforms. The library:

- provides a fast and accurate platform for calculating discrete FFTs.
- works on CPU or GPU backends.
- supports in-place or out-of-place transforms.
- supports 1D, 2D, and 3D transforms with a batch size that can be
  greater than 1.
- supports planar (real and complex components in separate arrays) and
  interleaved (real and complex components as a pair contiguous in
  memory) formats.
- supports dimension lengths that can be any combination of powers of
  2, 3, 5, 7, 11 and 13.
- Supports single and double precision floating point formats.
