FFTX is the exascale follow-on to the FFTW open-source discrete Fast Fourier Transform (FFT) package for executing the FFT as well as higher-level operations composed of linear operations combined with discrete Fourier transforms. It was developed as a cooperative effort between Lawrence Berkeley National Laboratory, Carnegie Mellon University, and SpiralGen, Inc.
Hardware/Software Co-Design for Exascale
Berkeley Lab supports three co-design centers under the Department of Energy’s Exascale Computing Project (ECP). It leads the Block-Structured Adaptive Mesh Refinement Co-Design Center and partners with other national labs and universities in the ExaGraph and ExaLearn Co-Design Centers.
ExaStar Takes Astrophysical Research to the Exascale
Berkeley Lab’s team of ExaStar researchers is focused on simulating explosive astrophysical events to address fundamental questions in nuclear astrophysics.
