pbzip2: Parallel BZIP2 0.9.6 Released

Posted by Sachin Garg on 11th February 2006 | Permanent Link

Jeff Gilchrist’s PBZIP2 is a parallel implementation of the bzip2 block-sorting file compressor that uses pthreads and achieves near-linear speedup on SMP machines. The output of this version is fully compatible with bzip2 1.0.2 (ie: anything compressed with PBZIP2 can be decompressed with bzip2).

This release fixes a major bug that caused some blocks to be missed by the decompression routine under certain conditions.

There was another release in Jan which fixed some major bugs that caused random segfaults and other problems with large files. It now defaults to silent operation like bzip2, and adds support for more win32 compilers like Borland.
