It +has been designed to transmit data to the processor cache faster than +the traditional, non-compressed, direct memory fetch approach via a +memcpy() OS call. Blosc is the first compressor (that I'm aware of) +that is meant not only to reduce the size of large datasets on-disk or +in-memory, but also to accelerate memory-bound computations. + +It uses the blocking technique so as to reduce activity in the memory +bus as much as possible. In short, this technique works by dividing +datasets in blocks that are small enough to fit in caches of modern +processors and perform compression / decompression there. It also +leverages, if available, SIMD instructions (SSE2, AVX2) and +multi-threading capabilities of CPUs, in order to accelerate the +compression / decompression process to a maximum. |
