127b27ec6Sopenharmony_ciname: lz4 227b27ec6Sopenharmony_civersion: 1.9.4 327b27ec6Sopenharmony_cisummary: Extremely Fast Compression algorithm 427b27ec6Sopenharmony_cidescription: > 527b27ec6Sopenharmony_ci LZ4 is lossless compression algorithm, providing compression 627b27ec6Sopenharmony_ci speed > 500 MB/s per core, scalable with multi-cores CPU. It features an 727b27ec6Sopenharmony_ci extremely fast decoder, with speed in multiple GB/s per core, typically 827b27ec6Sopenharmony_ci reaching RAM speed limits on multi-core systems. 927b27ec6Sopenharmony_ci . 1027b27ec6Sopenharmony_ci Speed can be tuned dynamically, selecting an "acceleration" factor which 1127b27ec6Sopenharmony_ci trades compression ratio for faster speed. On the other end, a high 1227b27ec6Sopenharmony_ci compression derivative, LZ4_HC, is also provided, trading CPU time for 1327b27ec6Sopenharmony_ci improved compression ratio. All versions feature the same decompression 1427b27ec6Sopenharmony_ci speed. 1527b27ec6Sopenharmony_ci . 1627b27ec6Sopenharmony_ci LZ4 is also compatible with dictionary compression, and can ingest any 1727b27ec6Sopenharmony_ci input file as dictionary, including those created by Zstandard Dictionary 1827b27ec6Sopenharmony_ci Builder. (note: only the final 64KB are used). 1927b27ec6Sopenharmony_ci . 2027b27ec6Sopenharmony_ci LZ4 library is provided as open-source software using BSD 2-Clause license. 2127b27ec6Sopenharmony_ciconfinement: strict 2227b27ec6Sopenharmony_cigrade: stable 2327b27ec6Sopenharmony_ci 2427b27ec6Sopenharmony_ciapps: 2527b27ec6Sopenharmony_ci lz4: 2627b27ec6Sopenharmony_ci command: usr/local/bin/lz4 2727b27ec6Sopenharmony_ci plugs: [home] 2827b27ec6Sopenharmony_ciparts: 2927b27ec6Sopenharmony_ci lz4: 3027b27ec6Sopenharmony_ci source: ../ 3127b27ec6Sopenharmony_ci plugin: make 32
