| OpenBLAS ChangeLog | 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) | |||||
| SPARC: | |||||
| - worked around an overflow error in the DNRM2 kernel | |||||
| POWER: | |||||
| - worked around an overflow error in the POWER6 DNRM2 kernel | |||||
| - 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 | |||||
| - RISCV: | |||||
| - fixed cpu autodetection logic | |||||
| ARMV8: | |||||
| - added an SBGEMM kernel for Neoverse N2 | |||||
| - worked around an overflow error in the DNRM2 kernel used on M1, NeoverseN1, ThunderX2T99 | |||||
| - added support for ARM64 systems running MS Windows | |||||
| - added support for cross-compiling to the GENERIC ARMV8 target under CMAKE (Windows/MSVC) | |||||
| - fixed a performance regression in the generic ARMV8 DGEMM kernel introduced in 0.3.19 | |||||
| - added initial support for the Apple M1 cpu under Linux | |||||
| - added initial support for the Phytium FT2000 cpu | |||||
| - added initial support for the Cortex A510, A710, X1 and X2 cpu | |||||
| - fixed an accidental mixup of cpu identifiers in the autodetection code introduced in 0.3.20 | |||||
| - fixed linking of Apple M1 builds on macOS 12 and later with recent XCode | |||||
| - made Neoverse N2 available in DYNAMIC_ARCH builds | |||||
| MIPS,MIPS64: | |||||
| - worked around an overflow error in the DNRM2 kernel | |||||
| LOONGARCH64: | |||||
| - worked around an overflow error in the DNRM2 kernel | |||||
| - added preliminary support for the LOONGSON2K1000 cpu | |||||
| - added DYNAMIC_ARCH support | |||||
