OpenBLAS ChangeLog

====================================================================

|
Version 0.3.21
|
||||||
|
07-Aug-2022
|
||||||
|
|
||||||
|
general:
|
||||||
|
- Updated the included LAPACK to Reference-LAPACK release 3.10.1
|
||||||
|
- when no Fortran compiler is available, OpenBLAS builds will now automatically
|
||||||
|
build LAPACK from an f2c-converted copy of LAPACK 3.9.0 unless the NO_LAPACK option
|
||||||
|
is specified
|
||||||
|
- similarly added C versions of the BLAS and CBLAS tests
|
||||||
|
- enabled building of the ReLAPACK GEMMT kernels when ReLAPACK is built
|
||||||
|
- function LAPACKE_lsame is now annotated with the GCC attribute "const" to aid static analyzers
|
||||||
|
- added USE_TLS to the list of options reported by the openblas_get_config() function
|
||||||
|
- CMAKE builds now support the BUILD_TESTING keyword (to disable the LAPACK testsuite) of Reference-LAPACK
|
||||||
|
- fixed CMAKE builds of the laswp_ncopy and neg_tcopy kernels
|
||||||
|
- removed the build system requirements for PERL (while keeping the original perl scripts as backup)
|
||||||
|
- handle building and running OpenBLAS on systems that report zero available cpu cores
|
||||||
|
- added SYMBOLPREFIX/SYMBOLSUFFIX handling for LAPACK 3.10.0 functions added in 0.3.20
|
||||||
|
- fixed linking of the utests on QNX
|
||||||
|
- Added support for compilation with the Intel ifx compiler
|
||||||
|
- Added support for compilation with the Fujitsu FCC compiler for Fugaku
|
||||||
|
- Added support for compilation with the Cray C and Fortran compilers
|
||||||
|
- reverted OpenMP threadpool behaviour in the exec_blas call to its state before 0.3.11, that is
|
||||||
|
the threadpool will no longer grow or shrink on demand as the overhead for this is too big at least with
|
||||||
|
GNU OpenMP. The adaptive behaviour introduced in 0.3.11 can still be requested at runtime by setting
|
||||||
|
the environment variable OMP_ADAPTIVE
|
||||||
|
- worked around spurious STFSM/CTFSM errors reported by the LAPACK testsuite
|
||||||
|
|
||||||
|
x86_64:
|
||||||
|
- fixed determination of compiler support for AVX512 and removed the 0.3.19
|
||||||
|
workaround for building SKYLAKEX kernels on Sandybridge hardware
|
||||||
|
- fixed compilation for the SKYLAKEX target with gcc 6
|
||||||
|
- fixed compilation of the CooperLake SBGEMM kernel with LLVM
|
||||||
|
- fixed compilation of the SkyLakeX small matrix GEMM kernels with LLVM or ICC
|
||||||
|
- fixed compilation of some BFLOAT16 kernels with CMAKE
|
||||||
|
- added support for the Zhaoxin/Centaur KH40000 cpu
|
||||||
|
- fixed a potential crash in the ZSYMV kernel used for all targets except generic
|
||||||
|
- fixed gmake compilation for DYNAMIC_ARCH with a DYNAMIC_LIST including ATOM
|
||||||
|
- fixed compilation of LAPACKE with the INTEGER64 option on Windows
|
||||||
|
- added support for cross-compiling to individual Intel or AMD targets using CMAKE
|
||||||
|
(previously only CORE2 supported, added targets are ATOM, PRESCOTT, NEHALEM, SANDYBRIDGE,
|
||||||
|
HASWELL,SKYLAKEX, COOPERLAKE, SAPPHIRERAPIDS, OPTERON, BARCELONA, BULLDOZER, PILEDRIVER,
|
||||||
|
STEAMROLLER,EXCAVATOR, ZEN)

|
||||||
|
POWER:
|
||||||
|

|
||||||
|
- fixed compilation on PPC440
|
||||||
|
- fixed a performance regression in the level1 BLAS on POWER10
|
||||||
|
- fixed the POWER10 ZGEMM kernel
|
||||||
|
- fixed singlethreaded builds for POWER10
|
||||||
|
- fixed compilation of the POWER10 DGEMV kernel with older gcc versions
|
||||||
|
- enabled compilation of the BFLOAT16 kernels by default

||||||
|
- enabled the small matrix kernels by default for DYNAMIC_ARCH builds
|
||||||
|
- added a workaround for a miscompilation of the CDOT and ZDOT kernels by GCC 12

||||||
|
|
||||||
|

|
||||||
|
- fixed cpu autodetection logic
|
||||||
|
|
||||||
|
ARMV8:

||||||
|
- added support for ARM64 systems running MS Windows
|
||||||
|
- added support for cross-compiling to the GENERIC ARMV8 target under CMAKE (Windows/MSVC)
