Parallel BZIP2 1.0.4 (Default branch)

ImagePBZIP2 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 or newer (ie: anything compressed with PBZIP2 can be decompressed with bzip2).License: BSD License (original)Changes:
Support was added for using pbzip2 with tar andfor all remaining bzip2 command line options, sopbzip2 can be used as a drop-in replacement forbzip2. A bug was fixed that would cause pbzip2 tocrash if detection of the number of processorsfailed. Compiling with uclibc is now supported.Image
