%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.
