%description
-Blosc is a high performance compressor optimized for binary data.
-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 to reduce activity on 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) and ulti-threading capabilities
-of CPUs, in order to accelerate the compression / decompression
-process to a maximum.
-
-Blosc is actually a metacompressor, that meaning that it can use a
-range of compression libraries for performing the actual
-compression/decompression. Right now, it comes with integrated support
-for BloscLZ (the original one), LZ4, LZ4HC, Snappy and Zlib. Blosc
-comes with full sources for all compressors, so in case it does not
-find the libraries installed in your system, it will compile from
-the included sources and they will be integrated into the Blosc
-library anyway. That means that you can trust in having all supported
-compressors integrated in Blosc in all supported platforms.
