Open Source SPIRAL System Open Source SPIRAL is available here under non-viral license (BSD-style license). See the SPIRAL User Manual for more information. Please let us know which parts of SPIRAL you are most interested in. Commercial support is available via SpiralGen, Inc. SPIRAL was developed over 20 years by the SPIRAL team under funding from DARPA (OPAL, DESA, HACMS, PERFECT, BRASS), NSF, ONR, DoD HPC, JPL, DoE, CMU SEI, Intel, Nvidia, and Mercury. The open sourcing of SPIRAL is an ongoing effort. The initial open source version of SPIRAL was supported by DARPA PERFECT.

FFTX and SPIRAL FFTX is the exascale follow-on to the FFTW open source discrete FFT package for executing the Fast Fourier Transform as well as higher-level operations composed of linear operations combined with DFT transforms. At the heart of FFTX is a build-time code generator, SPIRAL, that produces very high performance kernels targeted to their specific uses and platform environments. Go to the FFTX project page. Online Generators We provide a number of online generators, which are easy and fun to use or play with.Online generators currently available DFT = discrete Fourier transform, DCT = discrete cosine transform.
