The right column "Pages" contains information about rocFFT building and design

Initially, rocFFT includes the following transformation features

• 1D, with 2D & 3D having some bugs for small sizes
• power of 2, 3, 5 and mix of them, from size 1 to 2^27. That is, the input sizes that can be written in the form 2^a × 3^b × 5^c. The smaller the prime factor, the better the performance, i.e., powers of two are fastest.
• Complex to Complex transforms for single and double precision
• In-place and out-of-place transforms
• Interleaved layout, planar layout is not supported currently
• unit (=1) and non-unit strides
