Description

I wonder if it would be realistic and/or a goal to make the library GPU compatible. With that I mean only the crucial part of applying a pre-computed plan to a CUDA / CU Array.

This is probably a bit tricky in the c library. While the FFTW parts could probably be bound to the appropiate CUDA implementations (there is cuFFT), it would need adjustments for the other plans. Personally I have no experience with CUDA in C, but in Julia a bit and looked at the old pure version of the SH plans and it seemed at least plausible that this would be doable there, but maybe I also overlooked something.

Research direction

No files, tests, or entry points are named. Start by mapping the C library's plan-application path and its FFTW dependencies, then assess whether cuFFT and the other plan operations can support CUDA/CU arrays. Done requires a defined GPU-compatible scope and a validated implementation for applying pre-computed plans.
