=============================================================== Announcing Blosc 1.1.3 A blocking, shuffling and lossless compression library ===============================================================
What is new? ============ Much improved compression ratio when using large blocks (> 64 KB) and high compression levels (> 6) under some circumstances (special data distribution). For more info, please see the RELEASE_NOTES.txt file. What is it? =========== Blosc (http://blosc.pytables.org) is a high performance compressor optimized for binary data. It has been designed to transmit data to the processor cache faster than the traditional, non-compressed, direct memory fetch approach via a memcpy() OS call. Blosc is the first compressor (that I'm aware of) that is meant not only to reduce the size of large datasets on-disk or in-memory, but also to accelerate object manipulations that are memory-bound. It also contains a filter for HDF5 (http://www.hdfgroup.org/HDF5) so that you can easily implement support for Blosc in your favourite HDF5 tool. Download sources ================ Please go to: http://blosc.pytables.org/sources/ and download the stable release from here. Blosc is distributed using the MIT license, see LICENSES/BLOSC.txt for details. Mailing list ============ There is an official Blosc blosc mailing list at: [email protected] http://groups.google.es/group/blosc ---- **Enjoy data!** -- Francesc Alted _______________________________________________ Hdf-forum is for HDF software users discussion.
