================================================= Intel(R) Intelligent Storage Acceleration Library

Build Status

ISA-L is a collection of optimized low-level functions targeting storage applications. ISA-L includes:

  • Erasure codes - Fast block Reed-Solomon type erasure codes for any encode/decode matrix in GF(2^8).

  • CRC - Fast implementations of cyclic redundancy check. Three different polynomials supported.

    • iscsi, ieee, t10dif

  • Raid - calculate and operate on XOR and P+Q parity found in common RAID implementations.

  • Compression - Fast deflate-compatible data compression.

See ISA-L for updates. For crypto functions see isa-l_crypto on github.

Build Prerequisites

ISA-L requires yasm version 1.2.0 or later or nasm v2.11.01 or later. Building with autotools requires autoconf/automake packages.

Building ISA-L

Autotools

To build and install the library with autotools it is usually sufficient to run the following:

./autogen.sh
./configure
make
sudo make install

Other targets include: make check, make tests, make perfs, make ex (examples) and make other.

Windows

On Windows use nmake to build dll and static lib:

nmake -f Makefile.nmake

Other targes include: nmake check.
