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 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).
