FFTX documentation
FFTX is the exascale follow-on to the FFTW open-source package for executing the discrete Fast Fourier Transform, as well as higher-level operations composed of FFTs and linear operators. It is based on SPIRAL, a build-time code generator that produces high-performance kernels targeted to specific uses and platform environments.
FFTX is being developed as a cooperative effort between Lawrence Berkeley National Laboratory, Carnegie Mellon University, and SpiralGen, Inc.
