and can throw some light.
I don't know the status of the project, but fftw is definitely still
widely used, and definitely works in 64b.
I've coded a small program that reads a vorticity field, uses FFTW2 to
send it from the physical to the spectral space and then computes its
energy spectrum. Everything works in my laptop (32 bit, Linux),
serial, threaded and mpi (using openmpi). In a 64 bit machine the mpi
version kaputs. Any thoughts?
32-64 problems usually stem from someone conflating ints and pointers.
we have fftw2 installed on all our machines, which are all 64b (for years).
no reports of problems.
I am also using fftw2 on our 64-bit Linux cluster without any issues
