v2.15 Intel Intelligent Storage Acceleration Library Release Notes
Open Source Version
=============================================================================
=============================================================================
RELEASE NOTE CONTENTS
=============================================================================
1. KNOWN ISSUES
2. FIXED ISSUES
3. CHANGE LOG & FEATURES ADDED
=============================================================================
1. KNOWN ISSUES
=============================================================================
* Only erasure code unit included in open source version at this time.
* Perf tests do not run in Windows environment.
* 32-bit lib is not supported in Windows.
=============================================================================
2. FIXED ISSUES
=============================================================================
v2.15
* Fix for windows register save in gf_6vect_mad_avx2.asm. Only affects windows
versions of ec_encode_data_update() running with AVX2. A GP register was not
properly restored resulting in corruption on return.
v2.14
* Building in unit directories is no longer supported removing the issue of
leftover object files causing the top-level make build to fail.
v2.10
* Fix for windows register save overlap in gf_{3-6}vect_dot_prod_sse.asm. Only
affects windows versions of erasure code. GP register saves/restore were
pushed to same stack area as XMM.
=============================================================================
3. CHANGE LOG & FEATURES ADDED
=============================================================================
v2.15
* Erasure code updates. New AVX512 versions.
* Nasm support. ISA-L ported to build with nasm or yasm assembler.
* Windows DLL support. Windows builds DLL by default.
v2.14
* Autoconf and autotools build allows easier porting to additional systems.
Previous make system still available to embedded users with Makefile.unx.
* Includes update for building on Mac OS X/darwin systems. Add --target=darwin
to ./configure step.
v2.13
* Erasure code improvments
- 32-bit port of optimized gf_vect_dot_prod() functions. This makes
ec_encode_data() functions much faster on 32-bit processors.
- Avoton performance improvements. Performance on Avoton for
gf_vect_dot_prod() and ec_encode_data() can improve by as much as 20%.
v2.11
* Incremental erasure code. New functions added to erasure code to handle
single source update of code blocks. The function ec_encode_data_update()
works with parameters similar to ec_encode_data() but are called incrementally
with each source block. These versions are useful when source blocks are not
all available at once.
v2.10
* Erasure code updates
- New AVX and AVX2 support functions.
- Changes min len requirement on gf_vect_dot_prod() to 32 from 16.
- Tests include both source and parity recovery with ec_encode_data().
- New encoding examples with Vandermonde or Cauchy matrix.
v2.8
* First open release of erasure code unit that is part of ISA-L.
