OpenBLAS ChangeLog
====================================================================
Version 0.3.10
14-Jun-2020
common:
* Improved thread locking behaviour in blas_server and parallel getrf
* Imported bugfix 394 from LAPACK (spurious reference to "XERBL"
due to overlong lines)
* Imported bugfix 403 from LAPACK (compile option "recursive" required
for correctness with Intel and PGI)
* Imported bugfix 408 from LAPACK (wrong scaling in ZHEEQUB)
* Imported bugfix 411 from LAPACK (infinite loop in LARGV/LARTG/LARTGP)
* Fixed mismatches between BUFFERSIZE and GEMM_UNROLL parameters that
could lead to crashes at large matrix sizes
* Restored internal soname in dynamic libraries on FreeBSD and Dragonfly
* Added API (openblas_setaffinity) to set the thread affinity on Linux
* Added initial infrastructure for half-precision floating point
(bfloat16) support with a generic implementation of SHGEMM
* Added CMAKE build system support for building the cblas_Xgemm3m
functions
* Fixed CMAKE support for building in a path with embedded spaces
* Fixed CMAKE (non)handling of NO_EXPRECISION and MAX_STACK_ALLOC
* Fixed GCC version detection in the Makefiles
* Allowed overriding the names of AR, AS and LD in Makefile builds
POWER:
* Fixed big-endian POWER8 ELFv2 builds on FreeBSD
* Fixed GCC version checks and DYNAMIC_ARCH builds on POWER9
* Fixed CMAKE build support for POWER9
* fixed a potential race condition in the thread buffer allocation
* Worked around LAPACK test failures on PPC G4
MIPS:
* Fixed a potential race condition in the thread buffer allocation
* Added support for MIPS 24K/24KE family based on P5600 kernels
MIPS64:
* fixed a potential race condition in the thread buffer allocation
* Added TARGET=GENERIC
ARMV7:
* Fixed a race condition in the thread buffer allocation
ARMV8:
* Fixed a race condition in the thread buffer allocation
* Fixed zero initialisation in the assembly for SGEMM and DGEMM BETA
* Improved performance of the ThunderX2 DAXPY kernel
* Added an optimized SGEMM kernel for Cortex A53
* Fixed Makefile support for INTERFACE64 (8-byte integer)
x86_64:
* Fixed a syntax error in the CMAKE setup for SkylakeX
* Improved performance of STRSM on Haswell, SkylakeX and Ryzen
* Improved SGEMM performance on SGEMM for workloads with ldc a
multiple of 1024
* Improved DGEMM performance on Skylake X
* Fixed unwanted AVX512-dependency of SGEMM in DYNAMIC_ARCH
builds created on SkylakeX
* Removed data alignment requirement in the SSE2 copy kernels
that could cause spurious crashes
* Added a workaround for an optimizer bug in AppleClang 11.0.3
* Fixed LAPACK test failures due to wrong options for Intel Fortran
* Fixed compilation and LAPACK test results with recent Flang
and AMD AOCC
* Fixed DYNAMIC_ARCH builds with CMAKE on OS X
* Fixed missing exports of cblas_i?amin, cblas_i?min, cblas_i?max,
cblas_?sum, cblas_?gemm3m in the shared library on OS
* Fixed reporting of cpu name in DYNAMIC_ARCH builds (would sometimes
show the name of an older generation chip supported by the same kernels)
IBM Z:
* Improved performance of SGEMM/STRMM and DGEMM/DTRMM on Z14
