Changelog for libopenblas_serial-devel-0.3.5-64.2.x86_64.rpm :

* Mon Jan 07 2019 Ismail Dönmez - 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.
* A pthreads key leakage (and associate crash on dlclose) in the USE_TLS codepath was fixed.
* Building of the utest cases on systems that do not provide an implementation of complex.h was fixed. x86_64:
* The SkylakeX code was changed to compile on OSX.
* Unwanted application of the -march=skylake-avx512 option to the common code parts of a DYNAMIC_ARCH build was fixed.
* Improved performance of SGEMM for small workloads on Skylake X.
* Performance of SGEMM and DGEMM was improved on Haswell. armv8:
* A configuration error that broke the CNRM2 kernel was corrected.
* Compilation of the GEMM kernels with CMAKE was fixed.
* DYNAMIC_ARCH builds are now available with CMAKE as well.
* Using CMAKE for cross-compilation to the new cpu TARGETs introduced in 0.3.4 now works. power:
* A problem in cpu autodetection for AIX has been corrected.
* Fri Dec 07 2018 Ismail Dönmez - 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.

* Older assembly mnemonics have been converted to UAL form to allow building with clang 7.0
* Tue Oct 09 2018 Dmitry Roshchin - 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

* Corrected xDOT behaviour with zero INC_X or INC_Y 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.
