Dear DSP and numerics folks,

You might be interested to know that a beta release of FFTW 3.3 is now
available from www.fftw.org, with the final 3.3 release scheduled for
July 25.  This release includes several major new features, including
support for 256-bit AVX instructions on recent Intel/AMD processors
and an MPI parallel interface.

Regards,

Steven G. Johnson
