plzip

Parallel, lossless data compressor based on the LZMA algorithm

Plzip is a massively parallel (multi-threaded), lossless data compressor based on the LZMA algorithm, with very safe integrity checking and a user interface similar to the one of gzip or bzip2. Plzip uses the lzip file format; the files produced by plzip are fully compatible with lzip-1.4 or newer.
