Tue Apr 30 07:42:06 UTC 2019 - Martin Liška <mliska@suse.cz>
- Update to version 0.3.6 (boo#1122186)
common:
* the build tools now check that a given cpu TARGET is actually valid
* the build-time check of system features (c_check) has been made
less dependent on particular perl features (this should mainly
benefit building on Windows)
* several problems with ReLAPACK and its integration were fixed,
including INTERFACE64 support and building a shared library
* building with CMAKE on BSD systems was improved
* a non-absolute SUM function was added based on the
existing optimized code for ASUM
* CBLAS interfaces to the IxMIN and IxMAX functions were added
* a name clash between LAPACKE and BOOST headers was resolved
* CMAKE builds with OpenMP failed to include the appropriate getrf_parallel
kernels
* a crash on thread (key) deletion with the USE_TLS=1 memory management
option was fixed
* restored several earlier fixes, in particular for OpenMP performance,
building on BSD, and calling fork on CYGWIN, which had inadvertently
been dropped in the 0.3.3 rewrite of the memory management code.
POWER:
* single precision BLAS1/2 functions have received optimized POWER8 kernels
* POWER9 is now a separate target, with an optimized DGEMM/DTRMM kernel

-------------------------------------------------------------------
Mon Jan 7 10:15:03 UTC 2019 - Ismail Dönmez <idonmez@suse.com>
- Update to versiom 0.3.5
common:
* Loop unrolling in TRMV has been enabled again.
* A domain error in the thread workload distribution for SYRK
has been fixed.
* gmake builds will now automatically add -fPIC to the build
options if the platform requires it.

-------------------------------------------------------------------
Fri Dec 7 12:29:27 UTC 2018 - Ismail Dönmez <idonmez@suse.com>
- Update to version 0.3.4
common:
* The new, experimental thread-local memory allocation had
inadvertently been left enabled for gmake builds in 0.3.3
despite the announcement. It is now disabled by default,
and single-threaded builds will keep using the old
allocator even if the USE_TLS option is turned on.
* OpenBLAS will now provide enough buffer space for at least
50 threads by default.
* The output of openblas_get_config() now contains the version
number.
* A serious thread safety bug in GEMV operation with small M and
large N size has been fixed.
* The code will now automatically call blas_thread_init after
a fork if needed before handling a call to
openblas_set_num_threads
* Accesses to parallelized level3 functions from multiple
callers are now serialized to avoid thread races
(unless using OpenMP).
* This should provide better performance than the
known-threadsafe (but non-default)
USE_SIMPLE_THREADED_LEVEL3 option.
* When building LAPACK with gfortran, -frecursive is now
(again) enabled by default to ensure correct behaviour.
* The OpenBLAS version cblas.h now supports both CBLAS_ORDER
and CBLAS_LAYOUT as the name of the matrix row/column order
option.
* Externally set LDFLAGS are now passed through to the final
compile/link
* steps to facilitate setting platform-specific linker flags.
* A potential race condition during the build of LAPACK
(that would usually manifest itself as a failure to build
TESTING/MATGEN) has been fixed.
* xHEMV has been changed to stay single-threaded for small
input sizes where the overhead of multithreading exceeds
any possible gains
* CSWAP and ZSWAP have been limited to a single thread
except on ARMV8 or ThunderX hardware with sizable input.
* Linker flags for the PGI compiler have been updated
* Behaviour of AXPY with zero increments is now handled
in the C interface, correcting the result on at least
Intel Atom.
* The result matrix from calling SGELSS with an all-zero
input matrix is now zeroed completely.
x86_64:
* Autodetection of AMD Ryzen2 has been fixed (again).
* CMAKE builds now support labeling of an INTERFACE64=1
build of the library with the _64 suffix.
* AVX512 version of DGEMM has been added and the
AVX512 SGEMM kernel has been sped up by rewriting
with C intrinsics
* Fixed compilation on RHEL5/CENTOS5
(issue with typename __WAIT_STATUS)
armv8:
* DYNAMic_ARCH support is now available for 64bit ARM
* cross-compiling for ARMV8 under iOS now works.
* cpu-specific code has been rearranged to make better
use of both hardware commonalities and model-specific
compiler optimizations.
* XGENE1 has been removed as a TARGET, superseded by the
improved generic ARMV8 support.
armv7:
* Older assembly mnemonics have been converted to UAL
form to allow building with clang 7.0
-------------------------------------------------------------------
Tue Oct 9 19:00:49 UTC 2018 - Dmitry Roshchin <dmitry_r@opensuse.org>
- Update to version 0.3.3
common:
* thread memory allocation has been switched back to the method
used before version 0.3.1 due to unexpected problems caused by
the new code under some circumstances.
* LAPACK PR272 has been integrated, which fixes spurious errors
in DSYEVR and related functions caused by missing conversion
from ILAENV to ILAENV_2STAGE in several _2stage routines.
x86_64
* added AVX512 implementations of SDOT, DDOT, SAXPY, DAXPY,
DSCAL, DGEMVN and DSYMVL
* added a workaround for a cygwin issue that prevented compilation
of AVX512 code
-------------------------------------------------------------------
Fri Aug 17 12:56:04 UTC 2018 - idonmez@suse.com

x86_64:
* Retired some older targets of DYNAMIC_ARCH builds to a
new option DYNAMIC_OLDER, this affects PENRYN,DUNNINGTON,
OPTERON,OPTERON_SSE3,BOBCAT,ATOM and NANO (which will still
be supported via the slower PRESCOTT kernels when this option
is not set)
* Added an option DYNAMIC_LIST that (used in conjunction with
DYNAMIC_ARCH) allows to specify the list of x86_64 targets to
include. Any target not on the list will be supported by
the Sandybridge or Nehalem kernels if available, or by Prescott.
* Improved SWITCH_RATIO on Haswell for increased GEMM throughput
* Added initial support for Intel Skylake X, including an AVX512
SGEMM kernel
* Added autodetection of Intel Cannon Lake series as Skylake X
* Added a default L2 cache size for hypervisors that return zero
