Parallel BZIP2 1.0.5 (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:
This release properly complains about trying to read or write compressed data to the terminal, and exits. It further fixes the CPU detection crash, and the Makefile has been updated to force deletion when cleaning.Image
