============================================================================= 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.
