| OpenBLAS ChangeLog | |||
| ==================================================================== | |||
| Version 0.3.30 | |||
| 16-Jun-2025 | |||
| general: | |||
| - fixed an installation problem with the thread safety test in gmake builds | |||
| - fixed spurious overwriting of an input array in complex GEMMT/GEMMTR | |||
| - fixed naming of GEMMTR in error messages from XERBLA | |||
| - fixed compilation of SBGEMMT/SBGEMMTR in CMake builds | |||
| - fixed the implementation of ?NRM2 to handle INCX=0 correctly | |||
| - removed tests for CSROT and ZDROT that relied on unspecified behavior | |||
| - fixed a performance regression in multithreaded GEMM that was particularly | |||
| serious on POWER targets | |||
| - fixed linking issues when using LLVM's flang-new with gmake | |||
| - fixed a potential thread safety problem with C11 atomic operations | |||
| - further improved the workload partitioning in parallel GEMM | |||
| - fixed omission of LAPACKE interfaces for CGESVDQ,CTRSYL3 and ?GEQPF in | |||
| CMake builds | |||
| - fixed mishandling of setting NO_LAPACK to FALSE, and incorrect dependencies | |||
| for LAPACK function SPMV in CMake builds | |||
| - added explicit CMake options for building LAPACKE and shared libraries | |||
| - simplified and improved handling of OpenMP options in CMake builds | |||
| - reworked Windows DLL generation in CMake builds to ensure correct symbol | |||
| renaming (pre/postfixing) and optional generation of PDB files for debugging | |||
| - updated the Perl script version of the gensymbol utility for use with | |||
| Windows-on-Arm | |||
| - Fixed building with (Mingw) gmake on Windows to ensure completeness of the | |||
| LAPACK included in the static library (potential race condition due to the | |||
| Windows version of the "ln" utility creating snapshot copies rather than links) | |||
| - fixed unwanted deletion of the lapacke_mangling.h file by "make clean" | |||
| - fixed potential duplication of a _64 suffix on library names in CMake builds | |||
| - fixed compilation of the C fallback copies of the LAPACK code with GCC 15 | |||
| - included fixed from the Reference-LAPACK project: | |||
| - fixed a truncated error message in the EIG part of the testsuite | |||
| (Reference-LAPACK PR 1119) | |||
| - fixed too strict check in LAPACKE_?gesdd_work (PR #1126) | |||
| - fixed memory corruption when calling ?GEEV with non-finite data (PR #1128) | |||
| - fixed missing initialization of a variable in C/GEQP3RK (PR #1131) | |||
| - fixed 2nd dimension chosen in C/ZUNMLQ transposition operation (PR #1135) | |||
| x86_64: | |||

| - introduced a stepwise increase of the thread count used for | |||
| SGEMM and SGEMV on NEOVERSEV1/V2 in relation to problem size | |||
| - introduced a stepwise increase of the thread count used for | |||
| DGEMV on NEOVERSEV1 in relation to problem size | |||
| - introduced a stepwise increase of the thread count used for | |||
| SDOT and DDOT on NEOVERSEV1 in relation to problem size | |||
| - worked around assembler limitations in LLVM for Windows-on-Arm | |||
| - enabled cpu type autodetection from the registry on Windows-on-Arm | |||
