OpenBLAS ChangeLog
====================================================================
Version 0.3.13
12-Dec-2020
common:
* Added a generic bfloat16 SBGEMV kernel
* Fixed a potentially severe memory leak after fork in OpenMP builds
that was introduced in 0.3.12
* Added detection of the Fujitsu Fortran compiler
* Added detection of the (e)gfortran compiler on OpenBSD
* Added support for overriding the default name of the library independently
from symbol suffixing in the gmake builds (already supported in cmake)
RISCV:
* Added a RISC V port optimized for C910V
POWER:
* Added optimized POWER10 kernels for SAXPY, CAXPY, SDOT, DDOT and DGEMV_N
* Improved DGEMM performance on POWER10
* Improved STRSM and DTRSM performance on POWER9 and POWER10
* Fixed segmemtation faults in DYNAMIC_ARCH builds
* Fixed compilation with the PGI compiler
x86:
* Fixed compilation of kernels that require SSE2 intrinsics since 0.3.12
x86_64:
* Added an optimized bfloat16 SBGEMV kernel for SkylakeX and Cooperlake
* Improved the performance of SASUM and DASUM kernels through parallelization
* Improved the performance of SROT and DROT kernels
* Improved the performance of multithreaded xSYRK
* Fixed OpenMP builds that use the LLVM Clang compiler together with GNU gfortran
(where linking of both the LLVM libomp and GNU libgomp could lead to lockups or
wrong results)
* Fixed miscompilations by old gcc 4.6
* Fixed misdetection of AVX2 capability in some Sandybridge cpus
* Fixed lockups in builds combining DYNAMIC_ARCH with TARGET=GENERIC on OpenBSD
ARM64:
* Fixed segmemtation faults in DYNAMIC_ARCH builds
MIPS:
* Improved kernels for Loongson 3R3 ("3A") and 3R4 ("3B") models, including MSA
* Fixed bugs in the MSA kernels for CGEMM, CTRMM, CGEMV and ZGEMV
* Added handling of zero increments in the MSA kernels for SSWAP and DSWAP
* Added DYNAMIC_ARCH support for MIPS64 (currently Loongson3R3/3R4 only)
SPARC:
* Fixed building 32 and 64 bit SPARC kernels with the SolarisStudio compilers
