Compression

pbzip2 – parallel implementation of the bzip2 block-sorting file compressor

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 v1.0.2 or newer (anything compressed with pbzip2 can be decompressed with bzip2).

PBZIP2 should work on any system that has a pthreads compatible C++ compiler (such as gcc).

Features include:

  • Compress files larger than 4GB.
  • Files are broken into pieces with each individual piece compressed. This enables compression to run faster on machines with multiple cores.
  • Provides near-linear speedup with multi-core machines and 5-10% speed on hyperthreaded machines.
  • Output is fully compatible with regular bzip2 data.
  • Quiet mode.
  • Cross-platform support – runs under Linux, macOS, and Windows.
