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
|
||||
