  • Bijective BWT (29 Comments)

    David Scott has written a bijective BWT transform, which brings all the advantages of bijectiveness to BWT based compressors. Among other things, making BWT more suitable for compression-before-encryption and also give (slightly) better compression.

  • Asymmetric Binary System (170 Comments)

    Jarek Duda’s “Asymmetric Binary System” promises to be an alternate to arithmetic coding, having all the advantages, but being much simpler. Matt has coded a PAQ based compressor using ABS for back-end encoding. Update: Andrew Polar has written an alternate implementation of ABS.

  • Precomp: More Compression for your Compressed Files (5 Comments)

    So many of today’s files are already compressed (using old, outdated algorithms) that newer algorithms don’t even get a chance to touch them. Christian Schneider’s Precomp comes to rescue by undoing the harm.

mpibzip2 - parallel bzip2 for cluster machines

Posted by Sachin Garg on 20th August 2007 | Permanent Link

Jeff Gilchrist has released mpibzip2, a parallel implementation of the popular bzip2 block-sorting file compressor that uses MPI and achieves significant speedup on cluster machines.

Similar to his pbzip2 multi-threaded bzip2, the output is fully compatible with bzip2. The results show a near linear speed-up for upto 30 nodes.

Source code is available under BSD style license.
