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 or newer (ie: anything compressed with PBZIP2 can be decompressed with bzip2).

n-ary Huffman Template Algorithm

n-ary Huffman Template Algorithm allows any kind of weights (costs, frequencies), including non-numerical ones. The {0, 1, ..., n-1} alphabet is used to encode messages. The built tree is an n-ary one. The algorithm is based on a set of template classes: Cell(SYMBOL, WEIGHT), Node(SYMBOL, WEIGHT), InternalNode (SYMBOL, WEIGHT), TerminalNode(SYMBOL, WEIGHT), BasicHuffmanTree(SYMBOL, WEIGHT, ARY), LoadedHuffmanTree(SYMBOL, WEIGHT, ARITY), and DriedHuffmanTree(WEIGHT, ARITY).

MPIBZIP2 is a parallel implementation of the bzip2 block-sorting file compressor that uses MPI and achieves significant speedup on cluster machines. The output of this version is fully compatible with bzip2 1.0.2 or newer (i.e. anything compressed with MPIBZIP2 can be decompressed with bzip2).
