OpenBLAS ChangeLog OpenBLAS ChangeLog
====================================================================
Version 0.3.8
9-Feb-2020
common:
` * LAPACK has been updated to 3.9.0 (plus patches up to
January 2nd, 2020)
* CMAKE support has been improved in several areas including
cross-compilation
* a thread race condition in the GEMM3M kernels was resolved
* the "generic" (plain C) gemm beta kernel used by many targets
has been sped up
* an optimized version of the LAPACK trtrs functions has been added
* an incompatibilty between the LAPACK tests and the OpenBLAS
implementation of XERBLA was resolved, removing the numerous
warnings about wrong error exits in the former
* support for NetBSD has been added
* support for compilation with g95 and non-GNU versions of ld
has been improved
* support for compilation with (upcoming) gcc 10 has been added
POWER:
* worked around miscompilation of several POWER8 and POWER9
kernels by older versions of gcc
* added support for big-endian POWER8 and for compilation on AIX
* corrected bugs in the big-endian support for PPC440 and PPC970
* DYNAMIC_ARCH support is now available in CMAKE builds as well
ARMV8:
* performance of DGEMM_BETA and SGEMM_NCOPY has been improved
* compilation for 32bit works again
* performance of the RPCC function has been improved
* improved performance on small systems
* DYNAMIC_ARCH support is now available in CMAKE builds as well
* cross-compilation from OSX to IOS was simplified
x86_64:
* a new AVX512 DGEMM kernel was added and the AVX512 SGEMM kernel
was significantly improved
* optimized AVX512 kernels for CGEMM and ZGEMM have been added
* AVX2 kernels for STRMM, SGEMM, and CGEMM have been significantly
sped up and optimized CGEMM3M and ZGEMM3M kernels have been added
* added support for QEMU virtual cpus
* a compilation problem with PGI and SUN compilers was fixed
* Intel "Goldmont plus" is now autodetected
* a potential crash on program exit on MS Windows has been fixed
x86:
* an unwanted case sensitivity in the implementation of LSAME
on older 32bit AMD cpus was fixed
zarch:
* Z15 is now supported as Z14
* DYNAMIC_ARCH is now available on ZARCH as well
