Intel(R) Intelligent Storage Acceleration Library

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. Six different polynomials supported.
  • iscsi32, ieee32, t10dif, ecma64, iso64, jones64.
• Raid - calculate and operate on XOR and P+Q parity found in common RAID implementations.
• Compression - Fast deflate-compatible data compression.
• De-compression - Fast inflate-compatible data compression.

Building ISA-L

Prerequisites

• Assembler: nasm v2.11.01 or later or yasm version 1.2.0 or later.
• Compiler: gcc, clang, icc or VC compiler.
• Make: GNU 'make' or 'nmake' (Windows).
• Optional: Building with autotools requires autoconf/automake packages.

Autotools

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

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

Makefile

To use a standard makefile run:

make -f Makefile.unx

Windows

On Windows use nmake to build dll and static lib:

nmake -f Makefile.nmake

Other make targets

Other targets include:

• make check : create and run tests
• make tests : create additional unit tests
• make perfs : create included performance tests
• make ex : build examples
• make other : build other utilities such as compression file tests
• make doc : build API manual
