====================================================================

|
Version 0.3.11
|
|
|
|
|
17-Oct-2020
|
|
|
|
|
|
|
|
|
|
common:
|
|
|
|
|
* API change:
|
|
|
|
|
the newly added BFLOAT16 functions were renamed to use the
|
|
|
|
|
letter "B" instead of "H" to avoid potential confusion with
|
|
|
|
|
the IEEE "half precision float" type, i.e. the 0.3.10
|
|
|
|
|
SHGEMM is now SBGEMM and the corresponding build option
|
|
|
|
|
was changed from "BUILD_HALF" to "BUILD_BFLOAT16".
|
|
|
|
|
* Reduced the default BLAS3_MEM_ALLOC_THRESHOLD (used as an upper
|
|
|
|
|
limit for placing temporary arrays on the stack) to be compatible
|
|
|
|
|
with a stack size of 1mb (as imposed by the JAVA runtime library)
|
|
|
|
|
* Added mixed-precision dot function SBDOT and utility functions
|
|
|
|
|
shstobf16, shdtobf16, sbf16tos and dbf16tod to convert between
|
|
|
|
|
single or double precision float arrays and bfloat16 arrays
|
|
|
|
|
* Fixed prototypes of LAPACK_?ggsvp and LAPACK_?ggsvd functions
|
|
|
|
|
in lapack.h
|
|
|
|
|
* Fixed underflow and rounding errors in LAPACK SLANV2 and DLANV2
|
|
|
|
|
(causing miscalculations in e.g. SHSEQR/DHSEQR, LAPACK issue #263)
|
|
|
|
|
* Fixed workspace calculation in LAPACK ?GELQ (LAPACK issue #415)
|
|
|
|
|
* Fixed several bugs in the LAPACK testsuite
|
|
|
|
|
* Improved performance of TRMM and TRSM for certain problem sizes
|
|
|
|
|
* Fixed infinite recursions and workspace miscalculations in ReLAPACK
|
|
|
|
|
* CMAKE builds no longer require pkg-config for creating the .pc file
|
|
|
|
|
* Makefile builds no longer misread NO_CBLAS=0 or NO_LAPACK=0 as
|
|
|
|
|
enabling these options
|
|
|
|
|
* Fixed detection of gfortran when invoked through an mpi wrapper
|
|
|
|
|
* Improve thread reinitialization performance with OpenMP xafter a fork
|
|
|
|
|
* Added support for building only the subset of the library required
|
|
|
|
|
for a particular precision by specifying BUILD_SINGLE, BUILD_DOUBLE
|
|
|
|
|
* Optional function name prefixes and suffixes are now correctly
|
|
|
|
|
reflected in the generated cblas.h
|
|
|
|
|
* Added CMAKE build support for the LAPACK and multithreading tests
|
|
|
|
|
|
|
|
|
|

|
|
* Added support for compilation with LLVM/clang
|
|
|
|
|
* Added support for compilation with NVIDIA/PGI compilers
|
|
|
|
|
* Fixed building on big-endian POWER8
|
|
|
|
|
* Fixed miscompilation of ZDOTC by gcc10
|
|
|
|
|
* Fixed alignment errors in the POWER8 SAXPY kernel
|
|
|
|
|
* Improved CPU detection on AIX
|
|
|
|
|
* Supported building with older compilers on POWER9
|
|
|
|
|
|
|
|
|
|
x86_64:
|
|

|
* Added support for Intel Cooperlake
|
|
|
|
|
* Added autodetection of AMD Renoir/Matisse/Zen3 cpus
|
|

|
|
* Added autodetection of Intel Comet Lake cpus
|
|
|
|
|
* Reimplemented ?sum, ?dot and daxpy using universal intrinsics
|
|
|
|
|
* Reset the fpu state before using the fpu on Windows as a workaround
|
|
|
|
|
for a problem introduced in Windows 10 build 19041 (a.k.a. SDK 2004)
|
|
|
|
|
* Fixed potentially undefined behaviour in the dot and gemv_t kernels
|
|
|
