| PackageDescription | high performance meta-compressor optimized for binary data (development files)
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
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 multi-threading capabilities of CPUs, in order to
accelerate the compression / decompression process to a maximum.
.
This package contains the development files required to build programs against
Blosc. |
