FPZIP: COMPRESSED LARGE MULTIDIMENSIONAL FLOATING-POINT ARRAYS

Open-source software for large multidimensional floating-point arrays


 1. Home
 2. Projects: Inspired R&D at the Heart of LLNL Computing

fpzip is a BSD-licensed open-source library for lossless or lossy compression of
large multidimensional floating-point arrays. Although written in C++, fpzip has
a C interface. fpzip is based on the algorithm described in the following paper:

Peter Lindstrom(link is external) and Martin Isenburg, “Fast and Efficient
Compression of Floating-Point Data(link is external),” IEEE Transactions on
Visualization and Computer Graphics(link is external), 12(5):1245–1250,
September–October 2006, doi:10.1109/TVCG.2006.143(link is external).

fpzip was primarily designed for lossless compression but also has provision for
lossy compression. For lossy compression, our zfp compressor often outperforms
fpzip.
