It has\nbeen designed to transmit data to the processor cache faster than the\ntraditional, non-compressed, direct memory fetch approach via a memcpy()\nOS call. Blosc is meant not only to reduce the size of large datasets\non-disk or in-memory, but also to accelerate memory-bound computations.\n\nIt uses the blocking technique so as to reduce activity in the memory\nbus as much as possible. In short, this technique works by dividing\ndatasets in blocks that are small enough to fit in caches of modern\nprocessors and perform compression/decompression there. It also\nleverages, if available, SIMD instructions (SSE2, AVX2) and\nmulti-threading capabilities of CPUs, in order to accelerate the\ncompression/decompression process to a maximum.\n","package_architecture":"amd64","stem":"blosc","readme":null,"dependencies":[{"path":"archivers/lz4","type":"library","package_spec":"","url":"/packages/release/archivers/lz4/"},{"path":"archivers/snappy","type":"library","package_spec":"","url":"/packages/release/archivers/snappy/"},{"path":"archivers/zstd","type":"library","package_spec":"","url":"/packages/release/archivers/zstd/"},{"path":"devel/cmake/core","type":"build","package_spec":"STEM->=4","url":"/packages/release/devel/cmake/core/"},{"path":"devel/ninja","type":"build","package_spec":"","url":"/packages/release/devel/ninja/"}],"reverse_dependencies":{"count":4,"url":"/packages/data/ae/ae447d26cc77666407d1520a3d1ae195e0a7e9df71d40c4598a2565834ad9188.json"},"categories":["archivers"],"flavors":[],"only_for_architectures":["aarch64","amd64","arm","i386","mips64","mips64el","powerpc","powerpc64","riscv64","alpha","hppa","sparc64"],"not_for_architectures":[]}}
