12============

14Everything :-) This is the first public release of a project that
15started more than a year ago and that, after very intensive testing
16(several hundreds of TB compressed and decompressed without a glitch),
17it is finally getting ready for public consumption.
18
19This is Release Candidate 1 for Blosc 1.0 release, so please test it
20and report back any problem you may have with it.

23What is it?
24===========
25
26Blosc [1]_ is a high performance compressor optimized for binary data.
27It has been designed to transmit data to the processor cache faster
28than the traditional, non-compressed, direct memory fetch approach via
29a memcpy() OS call.  Blosc is the first compressor (that I'm aware of)
30that is meant not only to reduce the size of large datasets on-disk or
31in-memory, but also to accelerate memory-bound computations.
32
33It uses the blocking technique (as described in [2]_) to reduce
34activity on the memory bus as much as possible.  In short, this
35technique works by dividing datasets in blocks that are small enough
36to fit in caches of modern processors and perform compression /
37decompression there.  It also leverages, if available, SIMD
38instructions (SSE2) and multi-threading capabilities of CPUs, in order
39to accelerate the compression / decompression process to a maximum.
