|
||||

|
||||
30-Jul-2018
|
||||

common:
|
||||
* fixes for regressions caused by the rewrite of the thread
|
||||
initialization code in 0.3.1
|
||||
|
||||
POWER:
|
||||
* fixed cpu autodetection for the BSDs
|
||||
|
||||
MIPS64:
|
||||
* fixed utest errors in AXPY, DSDOT, ROT and SWAP
|
||||
|
||||
x86_64:
|
||||
* added autodetection of AMD Ryzen 2
|
||||
* fixed build with older versions of MSVC
|
||||
|
||||
====================================================================
|
||||
Version 0.3.1
|
||||
01-Jul-2018
|
||||
|
||||
common:
|
||||
* rewritten thread initialization code with significantly reduced overhead
|
||||
* added CBLAS interfaces to the IxAMIN BLAS extension functions
|
||||
* fixed the lapack-test target
|
||||
* CMAKE builds now create an OpenBLASConfig.cmake file
|
||||
* ZAXPY now uses a single thread for small input sizes
|
||||
* the LAPACK code was updated from Reference-LAPACK/lapack#253
|
||||
(fixing LAPACKE interfaces to Aasen's functions)
|
||||
|
||||
POWER:
|
||||
* corrected CROT and ZROT behaviour with zero INC_X
|
||||
|
||||
ARMV7:
|
||||
* corrected xDOT behaviour with zero INC_X or INC_Y
|
||||
|
||||
x86_64:
|
||||
* retired some older targets of DYNAMIC_ARCH builds to a new option DYNAMIC_OLDER,
|
||||
this affects PENRYN,DUNNINGTON,OPTERON,OPTERON_SSE3,BOBCAT,ATOM and NANO
|
||||
(which will still be supported via the slower PRESCOTT kernels when this option is not set)
|
||||
* added an option DYNAMIC_LIST that (used in conjunction with DYNAMIC_ARCH) allows to
|
||||
specify the list of x86_64 targets to include. Any target not on the list will be supported
|
||||
by the Sandybridge or Nehalem kernels if available, or by Prescott.
|
||||
* improved SWITCH_RATIO on Haswell for increased GEMM throughput
|
||||
* added initial support for Intel Skylake X, including an AVX512 SGEMM kernel
|
||||
* added autodetection of Intel Cannon Lake series as Skylake X
|
||||
* added a default L2 cache size for hypervisors that return zero here (Chromebook)
|
||||
* fixed a name clash with recent Windows10 headers that broke the build with (at least)
|
||||
recent mingw from MSYS2
|
||||
* fixed a link error in mixed clang/gfortran builds with OpenMP
|
||||
* updated the OSX deployment target to 10.8
|
||||
* switched on parallel make for builds on MS Windows by default
|
||||
|
||||
x86:
|
||||
* fixed SSWAP and DSWAP behaviour with zero INC_X and INC_Y
|
||||

||||

|
||||
Version 0.3.0
|
||||
23-May-2108
|
||||
|
||||
common:
|
||||
* fixed some more thread race and locking bugs
|
||||
* added preliminary support for calling an OpenMP build of the library from multiple threads
|
||||
* removed performance impact of thread locks added in 0.2.20 on OpenMP code
|
||||
* general code cleanup
|
||||
* optimized DSDOT implementation
|
||||
* improved thread distribution for GEMM
|
||||
* corrected IMATCOPY/OMATCOPY implementation
|
||||
* fixed out-of-bounds accesses in the multithreaded xBMV/xPMV and SYMV implementations
|
||||
* cmake build improvements
|
||||
* pkgconfig file now contains build options
|
||||
* openblas_get_config() now reports USE_OPENMP and NUM_THREADS settings used for the build
|
||||
* corrections and improvements for systems with more than 64 cpus
|
||||
* LAPACK code updated to 3.8.0 including later fixes
|
||||
* added ReLAPACK, a recursive implementation of several LAPACK functions
|
||||
* Rewrote ROTMG to handle cases that the netlib code failed to address
|
||||
* Disabled (broken) multithreading code for xTRMV
|
||||
* corrected prototypes of complex CBLAS functions to make our cblas.h match the generally accepted standard
|
||||
* shared memory access failures on startup are now handled more gracefully
|
||||
* restored utests from earlier releases (and made them pass on all affected systems)
|
||||
|
||||
SPARC:
|
||||
* several fixes for cpu autodetection
|
||||
|
||||
POWER:
|
||||
* corrected vector register overwriting in several Power8 kernels
|
||||
* optimized additional BLAS functions
|
||||
|
||||
ARM:
|
||||
* added support for CortexA53 and A72
|
||||
* added autodetection for ThunderX2T99
|
||||
* made most optimized kernels the default for generic ARMv8 targets
|
||||
|
||||
x86_64:
|
||||
* parallelized DDOT kernel for Haswell
|
||||
* changed alignment directives in assembly kernels to boost performance on OSX

|
||||
* updated compiler options to work with Intel release 2018
