We are porting a big plasma physics package from a Cray XMP-48 to
our Snakes and need the fastest possible FFT (one and two dimensional).
I am pretty sure that with the routines in -lvec you can write very
efficient code.  Anybody done this?

Prefer 2D FFT C code which is based on complex variables.

Thanks!
