OpenBLAS ChangeLog
====================================================================
Version 0.3.4
02-Dec-2018
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)
POWER:
* added support for building on AIX (with gcc and GNU tools from AIX Toolbox).
* CPU type detection has been implemented for AIX.
* CPU type detection has been fixed for NETBSD.
MIPS64:
* AXPY on LOONGSON3A has been corrected to pass "zero increment" utest.
* DSDOT on LOONGSON3A has been fixed.
* the SGEMM microkernel has been hardened against potential data loss.
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
* Cross compiling LAPACKE for Android has been fixed again (broken by
update to LAPACK 3.7.0 some while ago).
