Metal.jl does not speed up FFT

@huangc

Thanks for your reply. I found this in the Apple Developer Documentation. Do you think this has the potential to become the equivalent of cuFFT?

That’s not a Metal library though, so should rather be added to GitHub - JuliaLinearAlgebra/AppleAccelerate.jl: Julia interface to the macOS Accelerate framework. In fact, it does already have some commented-out code for FFT, https://github.com/JuliaMath/AppleAccelerate.jl/blob/d46c7fa39fc07fc257d07d7bbe6c64d35046e0e9/src/DSP.jl#L387-L425, so maybe you could start there.
