Hi everyone, I'm recently using r-2-r cosine FFT in my poisson solver. AndI wasconfused abouthow to chose fromTT routines, DFT routines and FFTw wrappers in MKL.
My detailed needs are:
1. Forward and backward staggered cosine transform
2. Multiple invoking of above FFT, which means I have many arrays of samelenth to transfer.
3. I want to use multi threads (8+ threads) to compute these transfers.
could someone give me instruction about which one is my best choice and what's the need of system environment(for example, the version of MKL).
