OpenMathLib/OpenBLAS v0.3.32

OpenBLAS 0.3.32 version

on GitHub

general:

• Moved the preliminary support for a Web Assembly target to its own WASM
  architecture and WASM128_GENERIC target
• Fixed a potential performance difference between dedicated compilation for
  a target and its representation in DYNAMIC_ARCH builds by making additional
  cpu-specific parameters available to the DYNAMIC_ARCH configuration
• Fixed the reimplementation of LAPACK ?GESV to conform to the reference (i.e.
  compute the LU factorization even when NRHS is zero)
• Improved the error message that is displayed when the compile-time allocation
  of memory buffers is exceeded
• Fixed a problem with non-serialized accesses to parallelized SYRK by concurrent
  callers
• Fixed an ABI mismatch in the internal version of CDOT/ZDOT used by the C fallback
  versions of the LAPACK source
• Improved the f_check script for detecting the Fortran compiler to handle embedded
  dashes in path names
• Fixed several memory access issues in the utests that were detected by Address
  Sanitizer
• Fixed Makefile errors in cases where only a subset of precision types was selected
• Fixed missing function errors in Makefile builds without LAPACK or without threads
• Fixed a syntax error in the benchmarks Makefile
• Fixed compiler warnings in the CBLAS testsuite
• Fixed the OpenMP compiler option used with the Intel Ifx compiler
• Updated the README sections on supported cpus and operating systems, and added
  notes pertaining to JAVA
• Updated the documentation page for supported BLAS-like extensions
• included fixes from the Reference-LAPACK project:
  • Improved step length selection in the fallback path of ?LAED4
    (Reference-LAPACK PR 1191)
  • Rounding up of LWORK and removal of redundant type conversions in the GVD
    functions (Reference-LAPACK PR 1202)
  • internal errors were getting ignored in calculation of selected eigenvalues
    (Reference-LAPACK PR 1204)

arm64:

• Fixed a potential miscompilation of the SDOT/DDOT/DSDOT kernels
• Fixed DYNAMIC_ARCH compilation with CMake and compilers lacking SVE support
• Improved the performance of BGEMM and SBGEMM kernels for Neoverse V2
• Added optimized SSUM and DSUM kernels for Neoverse N1
• Added preliminary support for Neoverse V3 cpus as NEOVERSEV2
• Added cpu autodetection of Cortex A725 and X925 cpus
• Fixed a CMake build problem with flang on Mac OS
• Fixed build problems with gcc versions 12 and earlier that do not support fp16
• Fixed compilation of GEMM kernels for VORTEXM4/ARMV9SME without multithreading
• Fixed the optimized CDOT/ZDOT kernel to compile with LLVM under Windows on Arm
• Renamed the copy of the DllMain function used in static linking on MS Windows to
  OpenBLASDllMain to avoid symbol name conflicts with other libraries

loongarch64:

• fixed POTRF returning wrong results on LA464 due to a wrong parameter setting

power:

• Fixed compilation problems caused by missing support for half-precision floats (FP16)
• Fixed a potential miscompilation of the POWER10 DGEMV kernel by limiting its optimization
  level
• Fixed a SCAL issue on PPCG4/PPC970 running Linux
• Worked around a SCAL issue on PPC970 running FreeBSD by switching to the generic C kernels

riscv64:

• Optimized the CROT/ZROT kernel for vector length 128 in the non-unit stride path
• Improved SBGEMM/SHGEMM and related helper functions for type conversion
• Fixed probing for BFLOAT16 support in DYNAMIC_ARCH cpu detection at runtime

x86_64:

• Fixed a potential miscompilation (by gcc 15.x) of the AVX512 SGEMM kernel for "small"
  matrix sizes
• Fixed the SROT and DROT kernels for Haswell to have consistent (FMA) rounding
  in the main loop and tail call
• Added automatic detection of Intel Arrow Lake H/U, Panther Lake and Jasper Lake
• Added automatic detection of Intel Emerald Rapids and upcoming cpu models
• Updated the cache size translation table in the cpu model autodetection code
• Improved cpu detection fallback to also include Nehalem as a non-AVX option
• Fixed a Makefile build issue with clang and the SkylakeX SGEMM kernel
• Renamed the copy of the DllMain function used in static linking on MS Windows to
  OpenBLASDllMain to avoid symbol name conflicts with other libraries

wasm:

• Added optimized intrinsics kernels for SGEMM and DGEMM as well as DOT, ROT and SUM
