FFTW Threads

[saurabbh14]

Currently, FFTW Threads are not supported by this cgo binding, right? Is it due to some cautious design decision?

FFTW 'threads' are for intra-fft parallelism, which is something I've never needed and no one has asked for. it could certainly be supported, but go routines do a great job at inter-fft parallelism and that has been sufficient for me at least.

I see. I'm adapting my old Fortran HPC code, which needs many multidimensional FFTs. So, I'm just playing around with performance optimization. I'm not sure if FFTW Threads (intra-fft parallelism) would truly be faster for my case, but I'm currently testing it with go-fftw plans.
