Intel(R) Intelligent Storage Acceleration Library

Build Status Package on conda-forge

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.

Also see: * ISA-L for updates. * For crypto functions see isa-l_crypto on github. * The github wiki including a list of distros/ports offering binary packages. * ISA-L mailing list. * Contributing.

Building ISA-L


  • Make: GNU 'make' or 'nmake' (Windows).
  • Optional: Building with autotools requires autoconf/automake packages.

x86_64: * Assembler: nasm v2.11.01 or later (nasm v2.13 or better suggested for building in AVX512 support) or yasm version 1.2.0 or later. * Compiler: gcc, clang, icc or VC compiler.

aarch64: * Assembler: gas v2.24 or later. * Compiler: gcc v4.7 or later.

other: * Compiler: Portable base functions are available that build with most C compilers.


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

sudo make install


To use a standard makefile run:

make -f Makefile.unx


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
