| 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 | |||
